Extracted text: Q2) a) an infinit line charge pL=20nc/m along z axis in free space, find the work done on a point carge Q=10nc if it carrying along a circular path of a radius p=2m from þ=n to p=2n at z=0 plane. b) a point charge of 2µc at origin in free spase , calculate V at point (3,6,0) if V=3V at (0,2,2)
