A conducting bar is pulled with a constant speed v on a smooth conducting rail. The region has a steady magnetic field of induction B as shown in the figure. If the speed of the bar is doubled then the rate of heat dissipation will

A conducting loop is pulled with a constant velocity towards a region of uniform magnetic field as shown in the figure then the current involved in the loop is (d gt r) -
