A coil of surface area 200 `cm^2` having 25 turns is held perpendicular to the magnetic field of intensity `0.02 "Wb/m"^2`. The resistance of the coil is 1`Omega` if it is removed from the magnetic field in 1s, the induced charge in the coil is ….. C.

A

1

B

0.01

C

0.1

D

0.001

Text Solution

Verified by Experts

The correct Answer is:
B

`Q=N (Deltaphi)/R` but `Deltaphi=AB-0=AB`
`therefore Q=(NAB)/R`
`=(25xx200xx10^(-4)xx0.02)/1`
`=100xx10^(-4)` =0.01 C
