Consider a circle of radius R. A point charge lies at a distance a from its center and on its axis such that \( \mathrm{R}=\mathrm{a} \sqrt{3} \). If electric flux passing through the circle is \( \phi \) then the magnitude of the point charge
\( P \)
is:- (A) \( \sqrt{3} \varepsilon_{0} \phi \)
(B) \( 2 \varepsilon_{0} \phi \)
(C) \( 4 \varepsilon_{0} \phi / \sqrt{3} \)
(D) \( 4 \varepsilon_{0} \phi \)
