a metal rod of resistance 20 ohms is fixed along the diameter of a conducting ring of radius 0.1m and lies on x- y plane. there is a magnetic field vectorB = (50T)kcap. the ring rotates with an angular velocity omega = 20 rad/sec about its axis . an external resistance of 10 ohms is connected across the centre of the ring and rim. find the current through external resistance
