A circular ring carries a charge Q, the variation of electric field with distance x measured from centre along axis for x<<R can be given as [R⟶ Radius of Ring]E∝1x2E∝xE∝1x3None of these

A circular ring carries a charge $Q$ , the variation of electric field with distance $x$ measured from centre along axis for $x << R$ can be given as [ $R ⟶$ Radius of Ring]
$E \propto \frac{1}{x^{2}}$
$E \propto x$
$E \propto \frac{1}{x^{3}}$
