electric field at all points on $y-$ axis is along $x-$ axis

Vedclass · Answer

If we take a point $M$ on the $X-$ axis as shown in the figure, then the net electric field is in $X-$ direction.

$	herefore $ Option $(a)$ is incorrect.

If we take a point $N$ on $Y-$ axis, we find net electric field along $+X$ direction. The same will be true for any point on $Y-$ axis. $(c)$ is a correct option.

${W_{ \propto 0}} = q({V_ \propto } - {V_0}) = q(0 - 0) = 0$

$	herefore $ $(b)$ is incorrect. The direction of dipole moment is from $-ve$ to $+ve$. Therefore $(d)$ is incorrect.

Two point charges $+q$ and $-q$ are held fixed at $(-d, 0)$ and $(d, 0)$ respectively of a $x -y$ coordinate system. Then
