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 = (phi_i - phi_f)/(R) = (NBA)/(R) = (25xx0.02xx200xx10^(-4))/(1)`
`= 25 xx 2 xx 2 xx 10^(-4)`
`= 10^(-2) C = 0.01 C`
