A U shape wire is formed by connecting a resistance R with two parallel conducting rod at its both ends and kept on a horizontal table A sliding wire PQ of length I and mass m can slide over the U Shape wire without friction This rod PQ is connected to a block of mass m through an insulating string going over a smooth pulley as shown A vertical magnetic field B is switched on and rod PQ is allowed to move from rest After some time it attains a constant velocity vo also called terminal velocity Now mass of the block is tripled it attain another terminal velocity VT Given B 10T 1 1 m vo 10 m s R 10 Q2 g Lung 777 The value of torminal volocity v ic 10 m s
