A thin spherical shel of radius R is charged with `+q` amount of charge. Use Gauss' law to find out the magnitude of the intensity of the electric field at a distance r from the centre of the shel, where (a) `rlt R`
and(b) `r gtR`
(ii) Show graphically how the magnitude of the intensity of the electric field changes with distance r from thke centre of the shell.

Explanation

(ii) the variation of field intensity with distance has been shown by the curved line AB.
