Problem

Two identical point charges

+q

and

-q

are separated by a distance

2a = 4\,\text{cm}

to form a dipole. Compare the magnitude of the electric field at point

A

(on the axial line,

10\,\text{cm}

from the center) to the magnitude of the electric field at point

B

(on the equatorial line,

10\,\text{cm}

from the center). Calculate the ratio

\frac{E_{\text{axial}}}{E_{\text{equatorial}}}
