well asume the conductor is spherical, and there's sphrical cavity in it. charge +3q in its origo, inner wall of conductor is 0-->a and outer wall is 0-->b.well if u draw Gaussian surface around the charge in the cavity then E is not zero, r<a, then there`d be potential difference inside the...
Homework Statement
Assume we have cavity in conductor. In the cavity we have +3q charge and conductor charge is distributed uniformly and is +7q.
With Gaus law we now that E=0 inside the conductor becaus Q enclosed is 0. But I have been wondering is there potential difference from inner...
