A square loop of side length ' a ' , mass ' m ' and Resistance ' R ' enters a uniform magnetic field (B=B0 (-k)) with velocity ' v° ' at t = 0 sec
Plot the variation of ' v ' with the distance from O ( Assume that ' v ' is enough so that the loop comes out of the field )

1a=-B2a2v/mR until the loop completely enters and leaves..... the forces on the upper and lower sides cancel each other and only one arm experiences the force....
in the middle journey.... no emf is induced....
write a=vdv/ds and solve the diff. eqn.... option A was correct i guess...
