Sharing Charges and Energy Conservation – Rankers Physics

Electric Potential Energy: Practice Problem & Solution

Assertion (A): When charges are shared between two bodies, there occurs no loss of charge, but there does occur a loss of energy. Reason (R): In case of sharing of charges energy of conservation fails.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution Explained:

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

Total charge is always conserved during sharing. Electrical potential energy may decrease and convert to heat, implying 'loss' of electrical energy (A is true). However, total energy is always conserved; (R) is false because energy conservation never fails.
