Answer:
The value is 
Explanation:
From the question we are told that
The current is 
The inductor is 
The voltage induced is 
Generally the emf induced is mathematically represented as

Here
is the time taken
=> 
=> 
=> 
Uniform circular motion is the motion in which an object covers equal distance in equal interval of time in a circular path and in non uniform motion object covers equal distance in unequal interval of time in a circular path
