Q. A coil of area of cross section 0.5 m2 among 10 turns is in a plane perpendicular to a magnetic field of 0.2 wb / m2. Compute the flux through the coil.
Magnetic flux φ = BA cos θ
= 10 X 0.5 X 0.2 X cos 0
= 1 wb.
a pendulum is timed ,first for 20 swings and then for 50 swings ; time for 20 swings = 17.4 sec and time for 50 sec = 43.2. calculate the average time per swing/
