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. `(4pi rho_(0)r)/(3epsilon_(0))((5)/(3)-(r)/(R))`
B. `(rho_(0)r)/(4epsilon_(0))((5)/(3)-(r)/(R))`
C. `(4rho_(0)r)/(3epsilon_(0))((5)/(4)-(r)/(R))`
D. `(rho_(0)r)/(3epsilon_(0))((5)/(4)-(r)/(R))`
