Question

A conducting rod of length l, mass m and resistance R is falling
freely through a uniform magnetic field B which is perpendicular to
the plane of paper Find terminal velocity of this rod

Dear Student,
let terminal velocity is v induced emf=vBland current=vBlRthen at this velocity magnetic field will equal to gravitational force so vBlRBl=mgv=RmgB2l2
Regard
