Magnetic flux and induced emf

Question

In figure, there are two sliders and they can slide on two frictionless parallel wires in uniform magnetic field B, which is present everywhere. The mass of each slider is m, resistance R and initially these are at rest. Now, if one slider is given a velocity v0 = 16 m s-1, what will be the velocity (in ms-1) of other slider after long time? (neglect the self induction)

Moderate
Solution

After long time, from conservation of momentum.

mv0=2mv;     v=v02=8ms-1
