Question
7.A uniform magnetic field B is normal to the surface generated by the track of width l and inclined at an angle theta with horizontal. An inductor of inductance L connects the tops ends as shown in the figure. A frictionless conducting rod of mass m is released at rest. There is no resistance anywhere. The rod is found to executed SHM. Then (A) Amplitude of oscillation is (B) Time period (C)equation of motion (D) current as function of distance x travelled by the rod on track (intial position being x=0 )
