Electric Potential: Practice Problem & Solution

Assertion (A): When an isolated charged body is connected to earth, all its charge flows to earth and it becomes electrically neutral. Reason (R): Electric potential of earth is non zero, so the body connected to earth should also attain zero potential.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Electric Potential. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is true as charges flow to earth. Reason (R) is false because earth's potential is considered zero.
