How does electric potential vary from point to point due to a thin charged spherical shell ? Draw a graph showing variation of potential with distance. |
|
Answer» SOLUTION : (a) Electric potential at the surface of a thin charged shell `V = Q/(4PI epsi_0R).` where Q=charge on spherical shell and R=radius of shell. (b) At a point situated outside the shell at a distancer from the centre of shell (r>R), electric potential `V = Q/(4pi epsi_0r)`  (c) However, inside the shell electric potential at all points is constant, which is equal to the potential at its surface i.e., `V = Q/(4pi epsi_0.R)` A graph showing variation of V with r is SHOWN in Fig. |
