Question

Electric field intensity at various points due to a uniformly charged spherical shell (thin & thick both).

Answer 1

It is easy to show that an area of surface density causes only one electric field (outside the sphere) in the form of a point charge at the center (use Gauss law and symmetry).

Similarly Gauss law predicts that continuous surface density area does not cause any area within it.

So if you calculate E (r), then you can imagine all the charges inside the ball, which are located in the center.

Answer 2

Electric Field Intensity at various points due to a uniformly charged spherical shell (thin & thick both).
