Two large conducting plates of a parallel plate capacitor are given charges Q and 3Q respectively. If the electric field in the region between the plates is E_0 , then the force of interaction between the plates is

Three concentric conducting spherical shells of radii R, R2 and 3R carry charges Q,-2Q and 3Q, respectively compute the electric field at r = (5)/(2) R

Three large conducting parallel sheets are placed at a finite from each other as shown in figure. Find out electric intensity at point A, B, C & D.

A charge +Q at A (see figure) produces electric field E and electric potential V at D . If we now put charges -2Q and +Q at B and C respectively, then the electric field and potential at D will be
