A metallic rod of mass per unit length 0.5 kg/m is lying horizontall – InterviewSolution

1.	A metallic rod of mass per unit length 0.5 kg/m is lying horizontally on a smooth inclined plane which makes an angle of 30^° withthe horizontal. The rod is not allowed to slidedown by flowing a current through it when magnetic field of induction 0.25 T is acting on it in the vertical direction. The current flowing inthe rod to keep it stationary is
