Question

If Ea be the electric field strength of a short dipole at a point on its axial line and Ee that on the equatorial line at the same distance, then (A) Ee=2 Ea (B) Ea=2 Ee (C) Ea=Ee (D) None of the above

We have Ea=(2 k p/r3) and Ee=(k p/r3) ⇒ Ea=2 Ee

Q. If $E_{a}$ 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

$E_{e} = 2 E_{a}$

$E_{a} = 2 E_{e}$

$E_{a} = E_{e}$

None of the above

We have $E_{a} = \frac{2 k p}{r ^{3}}$ and $E_{e} = \frac{k p}{r ^{3}} \Rightarrow E_{a} = 2 E_{e}$

Q. If Ea​ be the electric field strength of a short dipole at a point on its axial line and Ee​ that on the equatorial line at the same distance, then

Ee​=2Ea​

Ea​=2Ee​

Ea​=Ee​
