Question

If $E_{a}$ and $E_{q}$ represent the electric field intensity due to a short dipole at a point on its axial line and on the equatorial line at the same distance '$r$' from the centre of the dipole, then}

• A. E_{a} = E_{q}
• B. E_{a} = \frac{1}{2} E_{q}
• C. E_{a} = \frac{1}{\sqrt{2 E_{q}
• D. E_{a} = 2 E_{q}

Hint:

For any short dipole at a fixed distance $r$, the field at an axial point is always double the field at an equatorial point.

Answer 1
