Question

A spherically symmetric charge distribution is characterised by a charge density having the following variations:
`rho(r)=rho_o (1-r/R)` for `r < R rho(r)=0` for `r ge R`
Where r is the distance from the centre of the charge distribution p, is a constant. The electric field at an internal point (r < R) is:

Options:
(a) `rho_0/(4epsilon_0) (r/3-r^2/(4R))` (b) `rho_0/(epsilon_0) (r/3-r^2/(4R))`
(c) `rho_0/(3epsilon_0) (r/3-r^2/(4R))` (d) `rho_0/(12epsilon_0) (r/3-r^2/(4R))`
