1.

A triangle loop as shown in the figure is started to being pulled out at `t=0` from a uniform magnetic field with a constant velocity `v`.Total resistance of the loop is constant and equals to `R`.Then the variation of power produced in the loop with time will be: A. linearly increasing with time till whole loop comes outB. increases parabolically till whole loop comes outC. P `alphat^(3)` till whole loop come outD. will be constant with time.
