rotor slip = 10.42 %
Frequency = 6.24hz
Explanation:
given data
synchronous speed = 1200 RPM
rotor rotating speed = 1075 RPM
solution
first we get here rotor slip that is
rotor slip = ( synchronous speed - rotor rotating speed ) ÷ synchronous speed .............................1
rotor slip = 
rotor slip = 0.10416
rotor slip = 10.42 %
and
frequency of the induced rotor voltage is
Frequency = rotor slip × 60
Frequency = 10.42 % × 60
Frequency = 6.24hz
