A shunt-connected a dc motor has zero rotational losses and

A shunt-connected a DC motor has zero rotational losses and RA = 0. Assume that RA and Radj is constant [except in part (d)] and that φ is directly proportion to field current. For VT= 200 V and Pout = 2 hp. The speed is 1200 rpm. What is the effect on IA and speed if :
a) The load torque doubles.
b) The load power doubles.
c) VT is changed to 100V and P out remains constant
d) RA + Radj is doubled in value and P out remains constant?
