(A): If two charges are kept in a conductor medium, then electric force acting between them is zero.
R: `F=F_(0)/k`, For conductors `k=infty`
`therefore F=F_(0)/infty=0`

A

Both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

Both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

C

Assertion is true, but the Reason is false.

D

Both Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Electric force F = eE, have values are same but directions are opposite for both and as `a = F/m` are different due to different mass. So, statement and reason are correct but not corelated.
