There are four situations given in column 1 involving a magnetic dipole of dipole moment \( \bar{\mu} \) placed in uniform external magnetic field B. Column II gives corresponding results. Match the situtations in column I with the corresponding results in column II
\( P \)
Column-1 Column-II
(A) Magnetic dipole moment \( \vec{\mu} \) is parallel
(p) foree on dipole is zero
W)
to uniform external magnetic field B (angle
between both vectors is zero)
(B) Magnetic dipole moment \( \vec{\mu} \), is perpendicular
(q) torque on dipole is zero
to uniform external magnetic field \( \bar{B} \)
(C) Angle between magnetic dipole moment \( \tilde{\mu} \)
(r) magnitude of torque is \( (\mu \mathrm{B}) \)
and uniform external magnetic field \( \vec{B} \) is acute
(D) Angle between magnetic dipole moment \( \mu \)
(s) potential energy of dipole due to
and uniform external magnetic ficld \( \overline{\mathrm{B}} \) is \( 180^{\circ} \).
external magnetic field is \( (\mu \mathrm{B}) \)
