I used the general formula of Electric field due to uniformly charged sphere and substituted charge = volume charge density x volume) and then volume charge density (row) = kr . I got, for rR, E inversely proportional to r .... but in ans it's given E inversely proportional to r^2 .. I have also attached how I solved.. could someone tell me where I hve misunderstood *correct option A*

    use integral formula for calculation taking dq element at distance r then integrate you will get correct option. You formula is only valid for constant charge density. hope you und...
