Electrostatics Question 117

Question: The electric field between the plates of a parallel plate capacitor when connected to a certain battery is $ E _{0} $ . If the space between the plates of the capacitor is filled by introducing a material of dielectric constant K without disturbing the battery connections, the field between the plates shall be [AMU (Med.) 2002]

Options:

A) $ KE _{0} $

B) $ E _{0} $

C) $ \frac{E _{0}}{K} $

D) None of the above

Show Answer

Answer:

Correct Answer: B

Solution:

In the presence of battery potential difference remains constant.

Also $ E=\frac{V}{d}, $

so E remains same.
