Question

A closed loop PQRS carrying a current is placed in a uniform magnetic field. If the magnetic forces on segments $PS, SR$ and $RQ$ are $F_{1}, F_{2}$ and $F_{3}$ respectively and are in the plane of the paper and along the directions shown, the directions shown, the force on the segment $QP$ is

∴ ​ F 4 ​ sin θ = F 2 ​ F 4 ​ cos θ = ( F 3 ​ − F 1 ​ ) F 4 ​ = ( F 3 ​ − F 1 ​ ) 2 + F 2 2 ​ ​ ​ For a closed loop there is no translation.
