Choose the correct statement(s) :-

Options:(select one or more)

Answer:

Solution:

(A) Correct: every point of the equatorial plane of a dipole is at the same potential (V = 0), so any ellipse drawn in that plane is equipotential.

(B) Wrong: at distance r from a small dipole, $E_{min} = \frac{K P}{r ^{3}}$ and $E_{ma x} = \frac{2 K P}{r ^{3}}$ ; another point at the same r can have field up to 10 N/C.

(C), (D) Wrong: in a non-uniform external field the net force or torque on a dipole can be non-zero.
