Assertion: Two positively and charged co...

Assertion: Two positively and charged conductors are put in contact, the common potential will be less than the initial value of one of the conductors.
Reason: Both conductors will attract each other.

A

If both assertion and reason are true and reson is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
We know that common potential will be between two initial values, so it will be less than the potential of one of the conductor. Since, both have positive charges, so they will repulse each other.
