A square frame of wire connected to a capacitor is kept in a magnetic field which varies with position as well as time and is given as \overrightarrow{B}=\alpha x t(-\hat{k}) as shown in figure, where \alpha is a constant. The charge on the capacitor at any time is \frac{n}{2} {C} \alpha l^{3}. Then find the value of 'n'.
