A closed loop $\displaystyle P Q R S$ carrying a current is placed in a uniform magnetic field. If the magnetic forces on segments $\displaystyle P S, S R$ and $\displaystyle R Q$ are $\displaystyle F_1, F_2$ and $\displaystyle F_3$ respectively and are in the plane of the paper and along the directions shown, the force on the segment $\displaystyle Q P$ is :Official answer
(3)
$\displaystyle \sqrt{\left(F_3-F_1\right)^2+F_2{ }^2}$
