Electric circuit is composed of three conducting rods MO, ON and PQ as shown in the figure. The resistance of the rods per unit length is known to be 1. The rod PQ slides as shown in the figure. At t=0, rod PQ is at O. The whole system is embledded ina uniform magnetic field B, which is directed perpendicularly into page. The induced electric current is:

Verified by Experts

The correct Answer is:
`(Bv)/(lambda(sqrt(2) + 1))(constant)`
Equivalent circuit :

`I = (BvL)/(R )` `rarr` `I = (B(2vt)v)/(2sqrt(2)vt lambda + 2vt lambda) `rarr` I = (2Bv vt)/(2vt lambda (sqrt (2) + 1))`
