Let there be a spherically symmetric charge distribution with charge density varying as `rho(r)=rho(5/4-r/R)` upto `r=R`, and `rho(r)=0` for `rgtR`, where r is the distance from the origin. The electric field at a distance r(rltR) from the origin is given by

A

`(rho _(0))/(4 epsi _(0)) ((r )/(3) - (r ^(2))/(4R))`

B

`(rho _(0))/(epsi _(0)) ((r )/(3) -(r ^(2))/(4R))`

C

`(rho _(0))/( 3 epsi _(0)) ((r )/(3) - (r ^(2))/(4R))`

D

`(rho _(0))/( 12 epsi _(0)) (((r )/(3) - r ^(2))/( 4R))`
