Answer:
Maximum emf in the coil is 100 volt
Explanation:
We have given number of loops in the coil N = 50
Cross sectional area 
Angular speed is given 
Magnetic field is given 
We have to find the maximum emf in the coil
Maximum emf in the coil is given by 

So maximum emf induced in the coil is 100 volt
