Four point charges \( -q,+q,+q \) and \( -q \) are placed on \( y \)-axis at \( y=-2 d, y=-d, y=+d \)
\( \mathrm{P} \) and \( y=+2 d \), respectively. The magnitude of \( \mathrm{WV} \) the electric field \( E \) at a point on the \( x \)-axis at \( x=D \), with \( D \gg d \), will behave as
(a) \( E \propto \frac{1}{D^{3}} \)
(b) \( E \propto \frac{1}{D} \)
(c) \( E \propto \frac{1}{D^{4}} \)
(d) \( E \propto \frac{1}{D^{2}} \quad \) (JEE Main)
