An electron is moving around a proton in an orbit of
\( \mathrm{P} \) radius \( 1 \AA \) and produces \( 16 \mathrm{~Wb} / \mathrm{m}^{2} \) of magnetic field
\( \mathrm{W} \) at the centre, then find the angular velocity of electron
(A) \( 10^{16} \mathrm{rad} / \mathrm{sec} \)
(B) \( 10^{17} \mathrm{rad} / \mathrm{sec} \)
(C) \( 10^{18} \mathrm{rad} / \mathrm{sec} \)
(D) \( 10^{19} \mathrm{rad} / \mathrm{sec} \)
