QUESTIONS:
Q2213) A point charge q is placed at the center of the cavity of a thin metal shell
which is neutral. Will a charge Q placed outside the shell feel an electric force?
Explain.
Q233) State clearly the difference between (a) electric potential and electric field,
(b) electric potential and electric potential energy.
Q238) Can two equipotential lines cross? Explain.
Q2316) If you know V at a point in space, can you calculate
E
at that point? If you
know
E
at a point, can you calculate V at that point? If not, what else must be known
in each case?
Q243) Suppose one of the plates of a parallelplate capacitor was moved so that the
area of overlap was reduced by half, but they are still parallel. How would this affect
the capacitance?
