A negatively charged metallic ball is supported on a rigid insulated stand.We wish to measure the electric field E at a point P in the same horizontal level as that of the metallic ball. To do so we put a positive charge q and measure F/q. The electric field at the point P is
a.) =F/q
b.)
c.) >F/q
d.) none of these
