A circular coil of $$500$$ turns of wire has an enclosed area of $$0.1$$ $$m2$$ per turn. It is kept $$pe{perpendicular$$ to a magnetic field of induction $$0.2$$ T and rotated by $$1800$$ about a diameter perpendicular to the field in $$0.1$$ s. How much charge will pass when the coil is connected to a galvanometer with a combined resistance of $$50$$ ohms?
