It is induced EMF of periodic EMI, So formula is:
E= NBAw 
Here w is angular speed.
So, E = 25×0.05×200×20/10000 =0.5V

It is induced emf of periodic EMI so formula is E=NBAW here it w is angular speed so = 25×0.05×200×20/10000 =0.5V ans here divided by 10000 becoz in ques area is given in cm so it is converted into m.
