A coil of surface area 100 `cm^2` having 50 turns is held perpendicular to the magnetic field of intensity 0.02 `"Wb m"^(-2)`. The resistance of the coil is 2 `Omega` . If it is removed from the magnetic field in 1s, the induced charge in the coil is ____

A

5 C

B

0.5 C

C

0.05 C

D

0.005 C

Text Solution

Verified by Experts

The correct Answer is:
D
Induced charge `Q=N/R(Deltaphi)=(NAB)/R`
`therefore Q=(50xx100xx10^(-4)xx0.02)/2`
`therefore` Q=0.005 C
