Electro Magnetic Induction And Alternating Currents Question 375

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 [MP PET 1997]

Options:

A) 0.2 C

B) 0.4 C

C) 2 C

D) 4 C

Show Answer

Answer:

Correct Answer: B

Solution:

ΔQ=NBAR(cosθ1cosθ2) =500×0.2×0.1(cos0cos180)50=0.4 C
