A circular coil opf `500` turns of wire has an enclosed area of `0.1 m^(2)` per turn. It is kept perpendicular to a magnetic field of induction `0.2 T` and rotated by `180^(@)` about a diameter perpendicular to the field in `0.1` sec. how much charge will pass when the coil is connected to a gavanometer with a combined resistance of `50 ohms`

Text Solution

Verified by Experts

`q=(phi_i-phi_f)/R=(NBA-(-NBA))/R=(2NBA)/R`
`q=(2xx500xx0.2 xx0.1)/(50)=0.4 C`
