Electrostatics Question 192
Question: Two charged spheres separated at a distance d exert a force $ F $ on each other. If they are immersed in a liquid of dielectric constant 2, then what is the force (if all conditions are same) [AIIMS 1997; MH CET 2003]
Options:
A) $ \frac{F}{2} $
B) $ F $
C) $ 2F $
D) $ 4F $
Show Answer
Answer:
Correct Answer: A
Solution:
$ F\propto \frac{1}{K} $ i.e. $ \frac{F _{medium}}{F _{air}}=K $
