Q13. The magnetic moment of a bar magnet is $0.5 \mathrm { Am } ^ { 2 }$. It is suspended in a uniform magnetic field of $8 \times 10 ^ { - 2 } \mathrm {~T}$. The work done in rotating it from its most stable to most unstable position is: (1) $8 \times 10 ^ { - 2 } \mathrm {~J}$ (2) $4 \times 10 ^ { - 2 } \mathrm {~J}$ (3) Zero (4) $16 \times 10 ^ { - 2 } \mathrm {~J}$ Q14.
