Potential at P due to sphere = V 2 = 4 o R q which is the same for all points inside the shell. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company. Since the potential in the interior of the spherical shell does not change (because the field is zero, E = d V d x ), the difference in potential between any two points in the interior is zero; this in other words means that no work is done in moving a charge inside the spherical shell. So inside of a sphere, there is no gravitational force at all! However, since the weight can be adequately secured, it is not necessarily hazardous. | Holooly.com Subscribe $4.99/month Un-lock Verified Step-by-Step Experts Answers. Wouldn't the potential at ANY point inside the sphere just be V0? So we expect that in a problem like this the potential might look di erent inside and outside the sphere. This applies to a hollow sphere with finite width as well, since we can write that potential as an integral over a bunch of spherical shells, all of which will contribute constants that don't depend on the position r r inside the sphere. As you point out, the, E, inside the shell is zero, so the potential does not change as you go in from the surface. How can we make a spherical shell uniformly charged? If in a microscopic field the Electric field vary from point to point inside shell? He didn't mention whether it was conducting or not (but I don't believe it matters, right?). As you are explicitly assigning the potential on the boundary, this is independent from the fact that the surface is conducting or not. It only takes a minute to sign up. I'm just asking about the inside of the sphere here. E=\frac{1}{4\pi \epsilon _{0}}\frac{q}{r^{2}}\acute{r}. Solution: For r > R, V = 4 o r Q In this region, spherical shell acts similar to point charge. For Arabic Users, find a teacher/tutor in your City or country in the Middle East. Prove that isomorphic graphs have the same chromatic number and the same chromatic polynomial. what you working as now? Step 3: Net potential at point P As potential is scalar quantity, so net potential at a point will be sum of potentials due to all the charge configurations. with boundary condition $\phi=\phi_0$ on the surface. right? Your 'professor' seems to be referring to a different problem to the one you are describing. I also figured out the problem, after integration: and I forgot to consider the different cases for when x > R (outside spherical shell) and x<R (inside). @SRIVISHNUBHARAT I am not sure what you mean by microscopic field. Why the electric potential inside a conductor doesn't equal zero? The potential is defined relative to the infinity - not relative to the center of the shell. Un-lock Verified Step-by-Step Experts Answers. Since the potential in the interior of the spherical shell does not change (because the field is zero, $E = -\frac{dV}{dx}$), the difference in potential between any two points in the interior is zero; this in other words means that no work is done in moving a charge inside the spherical shell. The best answers are voted up and rise to the top, Not the answer you're looking for? This equation computes the potential energy due to the gravitational attraction between a point mass and a spherical hollow shell mass when the point mass lies inside the spherical shell. Would the answer matter depending on whether the surface is a conductor on insulator, even? Why doesn't the magnetic field polarize when polarizing light? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. You seem to be attempting to use Coulomb's law; but that is a bad idea. V(r)=\frac{-1}{4\pi \epsilon _{0}}\int_{\infty }^{R}{\frac{q}{\acute{r}^{2}} }d\acute{r}\int_{R}^{r}{(0)d\acute{r}} = \frac{1}{4\pi \epsilon _{0}}\frac{q}{\acute{r}}\mid ^{R}_{\infty } +0=\frac{1}{4\pi \epsilon _{0}}\frac{q}{R}. In that case: You haven't said anything about the charge outside of the shell. There are two ways of answering your question. If the magnitude of the electric field inside a uniformly charged spherical shell is zero then is how potential a non-zero constant equal to the potential of shell itself? For r R, The electrostatic potential on the surface of a charged conducting sphere is 100 V. Two statements are made in this regard. Making statements based on opinion; back them up with references or personal experience. The book says that a hollow charged sphere has an equal potential at all points on and inside the sphere but the points inside the sphere have zero net electric field for they have no charge. Inside the sphere, the field is zero, therefore, no work needs to be done to move the charge inside the sphere and, therefore, the potential there does not change. Do bracers of armor stack with magic armor enhancements and special abilities? For points outside the sphere (r > R). And the relation between the electric potential and the electric field is, Now, the value of the electric field due to spherical shell at point Poutside the sphere will be calculated by the formula. where q is the total charge on the sphere. The second way assumes that you mean the potential is zero at infinity. If I placed a second uniformly charged shell out at radius \acute{R}\gt R, the potential inside R would change, even though the field would still be zero.

The potential at a point in space is a property of that location. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. the object. This means that you do no work to move a charge from one point to another - which is the definition of "constant potential". If there are charges inside the sphere the potential is different, and can be constructed, for example, using the image charges method. I don't know if this helps but consider that since the shell is conducting and grounded the field outside should be zero as should be the potential. Suppose that we have a hollow sphere (spherical shell) whose surface is held at some constant potential V0. The fact that the field is zero indicates that the potential is constant. Why is the overall charge of an ionic compound zero? Why would Henry want to close the breach? Connect and share knowledge within a single location that is structured and easy to search. My professor said that "potential is something you can be "flexible" with and if you can set it equal to zero, why don't you?"
