Some charge is being given to a conductor. Then its potential is
maximum at surface
maximum at centre
remain same throughout the conductor
maximum somewhere between surface and centre
Can the potential function have a maximum or minimum in free space ? Explain.
A table tennis ball which has been covered with conducting paint is suspended by a silk thread so that it hang between two plates, out of which one is earthed and other is connected to a high voltage generator. This ball
Consider a sphere of radius $R$ with uniform charge density and total charge $Q$. The electrostatic potential distribution inside the sphere is given by $\theta_{(r)}=\frac{Q}{4 \pi \varepsilon_{0} R}\left(a+b(r / R)^{C}\right)$. Note that the zero of potential is at infinity. The values of $(a, b, c)$ are
The figure shows a nonconducting ring which has positive and negative charge non uniformly distributed on it such that the total charge is zero. Which of the following statements is true?
If eight identical drops are joined to form a bigger drop, the potential on bigger as compared to that on smaller drop will be
