Q5
A square loop of mass M side 'a', and carrying current i0 lies in the x-y plane as shown in the figure. It is hinged at y-axis so that it can freely route about it. Moment of inertia of the loop about an axis through its c.m. and normal to its plane is equal to γMa2. At t=0, an external magnetic field of induction B is applied along +ve x axis. The initial angular acceleration of the loop is equal to
