Assertion: The potential of grounded obj...

Assertion: The potential of grounded object is taken to be zero.
Reason: Capacitance of the earth's very large.

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:
A
Earth is good conductor of very large size. The capacitance of eatrh is very large. If some charge is given to earth or some charge drawn from earth. It does not effect the original potential. Thus, the potential of grounded object is supposed to be zero.
