What will be the potential at the middle spherical shell in the previous example? |
|
Answer» Solution :Note that the MIDDLE spherical shell is outside the spherical shell of radius a, and inside the spherical shell of radius c. For outside points potential is same as that of point charge as if it were placed at the centre of the shell, but for points inside potential is same as that on the surface. `V=(1)/(4PI epsilon_(0)) (q_(1))/(b)+(1)/(4pi epsilon_(0)) (q_(2))/(b)+(1)/(4pi epsilon_(0)) (q_(3))/(c )` |
