One end of a horizontal track of gauge and negligible resistance is connected to a capacitor of capacitance C charged to voltage Vo The inductance of the assembly is negligible The system is placed in a homogenous vertical magnetic field of induction B as shown in the figure A frictionless conducting rod of mass m and resistance R is placed perpendicularly onto the track The polarity of the capacitor is such that the rod is repelled from the capacitor when the switch is turned over What is the maximum velocity of the rod S X X A C B CV m B C B CV 2m B C V X X X E R X X X XBX B D l X 2B CV m B C B CV m 2B C
