Question

The electric field due to uniformly charged sphere of radius `R` as a function of the distance from its centre is represented graphically by
A.
B.
C.
D.

Answer 1

Correct Answer - b
`E_("inside")= (rho)/(3epsilon_(0))r (r lt R)`
`E_("outside")= (rhoR^(3))/(3epsilon_(0)r^(2)) (r ge R)`
i.e., inside the uniformly charged sphere field varies linearly `(E prop r)` with distance and outside varies according to `E prop 1/(r^(2))`
