14. Initially plane of coil is parallel to the uniform magnetic field $B$. In time $\Delta t$ it makes to perpendicular to the magnetic field, then charge flows in $\Delta t$ depends on this time as: (1999)

$\propto \Delta t$

$\propto \frac{1}{\Delta t}$

$\propto (\Delta t)^0$

$\propto (\Delta t)^2$

Solution:

The total charge flowing through the circuit is given by $Q = \frac{\Delta \Phi}{R}$.
This expression shows that the induced charge depends only on the net change in magnetic flux and resistance.
It is independent of the time interval $\Delta t$, meaning it is proportional to $(\Delta t)^0$.
