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

Solution Explained:

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.
