A moving coil galvanometer consists of a coil of N turns are area A suspended by a thin phosphor bronze strip in radial magnetic field B. The moment of inertia of the coil about the axis of rotation is l and c is the torsional constant of the phosphor bronze strip. When a current i is passed through the coil, it deffects through an angle `theta`
When a charge Q is almost instantly through the coil the angular speed `omega` acquired by the coil is

A

`Q_("max") = omega sqrt((l)/(C))`

B

`Q_("max") = (1)/(C) sqrt(l omega)`

C

`Q_("max") = l sqrt((omega)/(C))`

D

`Q_("max") = omega sqrt(lC)`
