`5xx10^(-4)` field lines are passing through a coil 1000 turn in certain time interval, the electromotive force of 5V is produced then the time interval will be _____

A

1 s

B

0.1 s

C

0.01 s

D

0.001 s

Text Solution

Verified by Experts

The correct Answer is:
B
`epsilon=(N Delta phi)/(Deltat)`
`therefore Deltat=(N Deltaphi)/epsilon=(1000xx5xx10^(-4))/5`=0.1 s
