Correct option is A)

Electric field on axis

E= r 1 2 ​ kq ​ − r 2 2 ​ kq ​ =kq( r 1 2 ​ r 2 2 ​ r 2 2 ​ −r 1 2 ​ ​ )=kq r 1 2 ​ r 2 2 ​ (r 2 ​ −r 1 ​ )(r 1 ​ +r 2 ​ ) ​ (r 2 ​ −r 1 ​ )=dr 1 ​ =r 2 ​ =r= r 3 2kqd ​ ∴E α r −3 E on radial axis E r ​ r>>d E net ​ = (r 2 + 4 d 2 ​ ) kg ​ r 2 + 4 d 2 ​ ​ 2 d ​ ​ = (r 2 + 4 d 2 ​ ) kq ​ r 2 + 4 d 2 ​ ​ 2 d ​ ​ E r ​ = r 3 kqd ​ ∴E α r −3
