A ball of radius r carries a positive charge whose volume charge density depends only on separation r from the ball's centre as =0(1rr)=0(1rr) where 00 is a constant. Assuming the relative permittivities of the ball and the environment to be equal to unity. The electric field at distance r1 from centre (for r1 < r) is
