Statement : Inside a charged conducting spherical shell electric potential at any point is (Kq)/( R) and at a point outside it, field is (Kq)/(r^(2)). Electri field inside the shell at any point is zero and outside it field is (Kq)/(r^(2)). Here K is (1)/(4piepsilon_(0))R. is the radius of shell and r the distance from centre of shell. Two concentric spherical shells of radii R and 2R have charges Q and 2Q as shown in figure. If we draw a graph between electric field E and distance r from the centre, it will be like : |
