A square loop ABCD of side length a and mass m of each side is kept in a uniform magnetic field region B B as shown in the figure The loop is constrained to rotate only about the y axis It rotates only due to the torque of the magnetic force acting on it Calculate its angular speed in rad s when it has rotated through an angle 90 Initially the loop was lying in the x y plane The loop is carrying current I as shown in 31B figure Given m 4
