# Mechanics + Magnetism = Mechatism 3

**Classical Mechanics**Level 5

Now If Lower cylinder is displace slightly to the rightward direction .And If Maximum velocity of lower cylinder is \({ V }_{ 1,max }\) .

Assume that whole system is placed in uniform magnetic field of strength B . which is perpendicular to the plane of cylinders ( - Z direction )

And If Magnitude of Motional EMF develop between the point P and Q just before the lower cylinder reaches it's maximum velocity is \({ E }_{ pq }\).

Then Find The value of \[\displaystyle{\cfrac { BR({ V }_{ 1,max }) }{ { E }_{ pq } }}\].
