Figure shows a conducting rod of length `l = 10 cm`, resistance `R` and mass `m = 100 mg` moving vertically downward due to gravity. Other parts are kept fixed. Magnetic filed is `B = 1 T`. `MN and PQ` are vertical, smooth, the capacitor is `C = 10mF`. The rod is released from rest. Find the maximum current (in mA) in the circuit.
