1.	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`A. `0.2 C`B. `0.4 C`C. `2 C`D. `4 C`
Answer» Correct Answer - B `DeltaQ=(NBA)/(R )(costheta_(1)-costheta_(2))` `=(500xx0.2xx0.1(cos0-cos180))/(50)=0.4C`
