Question
CBSEENPH11019554

Can external work change the potential energy of the system? 

Solution
Work done by an external agent can change the potential energy of the system. 
Positive external work leads to an increase in the potential energy of the system. 
For example, we have an apple that is lying on the ground. The work done by an external agent to pick the apple from the ground or lift the apple is stored as the gravitational potential energy.
