Vedclass · Answer

(A) The electric field due to a dipole at any point on its equatorial plane is directed anti-parallel to the dipole moment vector $\vec{p}$.The dipole moment vector $\vec{p}$ is directed from $-q$ to $+q$,which is along the negative $x$-axis (from right to left).Therefore,the net electric field $\vec{E}_{	ext{net}}$ at point $M$ on the equatorial plane is directed parallel to the dipole moment vector,i.e.,from $+q$ to $-q$,which is along the positive $x$-axis.Since the net electric field vector $\vec{E}_{	ext{net}}$ points along the positive $x$-axis,the angle $\phi$ it makes with the $x$-axis is $0^{\circ}$.

Consider two charges $+q$ and $-q$ $(q > 0)$ placed at a distance $2a$ from each other. At the point $M$ (see figure below),the electric field makes an angle $\phi$ with the $x$-axis. The correct value of $\phi$ is (in $^{\circ}$)
