Electrostatics Question 302

Question: 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 [MP PET 1999; J & K CET 2004]

Options:

A) $ E _{e}=2E _{a} $

B) $ E _{a}=2E _{e} $

C) $ E _{a}=E _{e} $

D) None of the above

Show Answer

Answer:

Correct Answer: B

Solution:

We have $ E _{a}=\frac{2kp}{r^{3}} $ and $ E _{e}=\frac{kp}{r^{3}}; $ $ E _{a}=2E _{e} $
