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} $
