A circuit ABCD is held perpendicular to the uniform magnetic field of  $B=5\times {10}^{-2}T$  extending over the region PQRS and B directed into the plane of the paper. The circuit is moving out of the field at a uniform speed of 0.2 ms^-1 for 1.5 s. During this time, the current in the $5\Omega$  resistor is
