1)two concentric hollow conducting spheres of radius r and R.the charge on outer shell is Q . what charge should be given to inner sphere so that the potential at any point P outside the outer sphere is zero? 2)the electric potential V at a point P(x,y,z) in space is given by V= 4x2 volt.electric field at a point (1m,0,2m) in V/m is?
