A circular coil of $$500$$ turns of wire has an enclosed area of $$0.1$$ $$m2$$ 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 galvanometer with a combined resistance of $$50$$ ohms

Question

A circular coil of $$500$$ turns of wire has an enclosed area of  $$0.1$$ $$m2$$ 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 galvanometer with a combined resistance of $$50$$ ohms
