XPQY is a vertical smooth long loop having a total resistance R where PX is parallel to QY and separation between them is . A constant magnetic field B perpendicular to the plane of the loop exists in the entire space. A rod CD of length L () and mass m is made to slide down from rest under the gravity as shown in figure. The terminal speed acquired by the rod is m/s. ( = acceleration due to gravity)
