N equally spaced charges each of value q , are placed on a circle of radius R . The circle rotates about its axis with an angular velocity $$\omega$$ as shown in the figure. A bigger Amperian loop B encloses the whole circle where as a smaller Amperian loop A encloses a small segment. The difference between enclosed currents, $$I_A - I_B$$, for the given Amperian loops is

A

$$ \frac{2\pi}{N}q\omega $$

B

$$ \frac{N^{2}}{2\pi}q\omega $$

C

$$ \frac{N}{\pi}q\omega $$

D

$$ \frac{N}{2\pi}q\omega $$
