Q. 14 A round rotor generator with internal voltage 
and X=1.1 p.u is connected to a round rotor synchronous motor with internal voltage 
and X=1.2p.u. The reactance of the line connecting the generator to the motor is 0.5 pu. When the generator supplies 0.5 pu power, the rotor angle difference between the machines will be
