AB is a resistance less conducting rod which forms a diameter of a conducting ring of radius r rotating in a uniform magnetic field as shown in figure. The resistors R1 and R2 do not rotate . Then the current through the resistor R1 is

An equilateral triangular loop ADC having some resistance is pulled with a constant velocity v out of a uniform magnetic field directed into the paper (figure). At time t=0 side DC of the loop is at edge of the magnetic field. The induced current (i) versus time (t) graph will be as
