Initially plane of coil is parallel to the uniform magnetic field B. In time `Deltat` it makes to perpendicular to the magnetic field, then charge flows in `Deltat` depends on this time as -A. `propDeltat`B. `prop(1)/(Deltat)`C. `prop(Deltat)^0`D. `prop(Deltat)^2`

Answer» Correct Answer - C
`therefore " " q=(Deltaphi)/R " " therefore q prop (Deltat)^@`
