Assertion: If the meduim between two charges is replaced by another medium of grater dielectric constant then the electric force between them decreases.
Reason: Electric dipole moment varies inversely as the dielectric constant.

Options

A. if both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
C. if Assertion is true, but the Reason is false.
D. if both Assertion and Reason are false

Answer

c

Explanation

In a medium,
`F_(m)= (F)/(K)`
From above expression it is quite clear that greater the value of `K` smaller is the force between the two charges. Electric dipole moment is directly proportional to dielectric constant.
