A) potential varies as\[\frac{1}{{{r}^{2}}}\]
B) potential is zero at all points on the right bisector
C) field varies as\[{{r}^{3}}\]
D) field is perpendicular to the axis of dipole
Correct Answer: B
Solution :
Magnetic field at P due to north & south pole can be resolved into components parallel to the axis of the dipole and along the bisector. Components along the, bisector cancel out The horizontal components add upYou need to login to perform this action.
