Pls sir help me in this question, I tried it many times but failed .I just have only one confusion in which rod emf is induced.It is from NCERT at your fingertipsQ-A metal rod of resistance 20ohm is fixed along a diameter of a conducting ring of radius 0.1m and lies on x-y plane.There is a magnetic field B=50T k^.The ring rotates with an angular velocity 20rad/sec about its axis.An external resistance of 10 ohm is connected across the centre of the ring and rim.The current through external resistance isAns-1/3A
