Q#1 DC Machines GATE EE 1999 NAT +2 marks -0 marks

A separately excited DC shunt motor is driving a fan load whose torque is proportional to the square of the speed. When 100V are applied to the motor, the current taken by the motor is 8A, with the speed being 500 rpm. At what applied voltage does the speed reach 750 rpm and then what is the current drawn by the armature? Assume the armature circuit resistance to be 1Ω. Neglect brush and mechanical losses
