Let there be a spherically symmetric charge distribution with charge density varying as rho (r) = rho_0((5)/(4) - (r)/(R) ) upto r = R, and rho (r) = 0 for r >R, where r is the distance from the origin. The electric field at a distance r (r

Answer»

`(4 PI rho_0r)/(3 epsi_0) ((5)/(3) -(R )/(R ))`
`(rho_0 r)/(4 epsi_0) ((5)/(3) -(r )/(R))`
`(4rho _0r)/(/( 3 epsi_0 )(5/4 - r/R)`
`(rho_0 r)/( 3 epsi_0) ((5)/(4) -r/R)`
