A copper connector of mass 
slides down two smooth copper bars, set at an angle 
to the horizontal, due to gravity (see figure). At the top the bars are interconnected through a resistance 
. The separation between the bars is 
. The system is located in a uniform magnetic field of induction 
, perpendicular to the plane in which the connector slides. The resistance of the bars, the connector and the sliding contacts, as well as the self-inductance of the loop are assumed to be negilible. If the connector is released from rest at

as shown in the figure. At the point of crossing the wires remain electrically insulated from each other. The entire loop lies in the plane (of the paper). A uniform magnetic field 
points into the plane of the paper. At 
in the magnetic field. Which of the following options is/are correct?
