Assertion (A): Magnetic field on the axial line at a certain distance is twice as compared to that on the equatorial line at the same distance.
Reason (R): Electric field due to a dipole varies inversely as the cube of the distance.
(A) Both A and R are true and R is the correct explanation of A.br(B) Both A and R are true, but R is not the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(E) Both A and R are false.
