For lowest potential energy configuration magnetic moments should be parallel Hence, PQ6 will be the lowest potential energy configuration.

Q. The figure below shows the various positions (labelled by subscripts) of small magnetized needles $P$ and $Q$ . The arrows show the direction of their magnetic moment. Which configuration corresponds to the lowest potential energy of all the configurations show?

$P Q_{3}$

$P Q_{4}$

$P Q_{5}$

$P Q_{6}$

For lowest potential energy configuration magnetic moments should be parallel Hence, $P Q_{6}$ will be the lowest potential energy configuration.
