If ${\mathrm{E}}_{\mathrm{a}}$ be the electric field strength of a short dipole at a point on its axial line and $E_e$ that on the equatorial line at the same distance, then

• A

  ${\mathrm{E}}_{\mathrm{e}}=2{\mathrm{E}}_{\mathrm{a}}$

• B

  ${\mathrm{E}}_{\mathrm{a}}=2{\mathrm{E}}_{\mathrm{e}}$

• C

  ${\mathrm{E}}_{\mathrm{a}}={\mathrm{E}}_{\mathrm{e}}$

• D

  None of the above
