Homework Answers
Electric field inside a solid conductor, positive or negative,
is zero.
As charges want to attain equilibrium so they come on surface , to minimize the repulsion among them. So, the total charge of a conductor resides on its surface and the net charge inside a conductor remains zero. Thus, field inside it is zero.

A positively charged ball is brought near to a neutral conductor, polarizing the conductor. Then the conductor is grounded, which allows negative charge to flow onto the conductor. See below positat entnas a) Now the positive ball is taken away, and then the ground connection is removed. Is the final charge on the conductor positive, negative, or neutral? Carefully explain your reasoning. b) What if, instead, the ground connection is removed first. and then the positive ball is taken away?...

1 (a) Explain why there is no electic field inside an uncharged, or statically charged, [2] conductor (b) An uncharged perfectly conducting solid sphere of radius a is placed with its centre at the origin in a region of uniform electric field E = E02. The presence of the sphere modifies the electric field (and the potential) i. Show that the initial potential in spherical coordinates is Vinit (T, 0, )Eor cos 0 everywhere (i.e. before the sphere was placed...
