MHT CET 2022 Physics question
The charge which will flow through a galvanometer of resistance connected to a circular coil 1000 turns wound on a wooden stick 20 mm in diameter, if a magnetic field B = 0.012 T parallel to the axis of the stick decreased suddenly to zero, is nearly
Answer: (C)
Solution
The induced charge is , independent of the time taken. The total resistance is . The coil area is m. The flux change is $ΔΦ = BA - 0 =
