Physics · WORK, ENERGY AND POWER

Given below are two statements: Statement I: When non-conservative forces act on a body, the total mechanical energy \( E = K + V \) is always conserved. Statement II: The work done by non-conservative forces is equal to the change in the total mechanical energy of the system, \( \Delta E = W_{nc} \). In the light of the above statements, choose the most appropriate answer from the options given below:

1. A
   Both Statement I and Statement II are correct.
2. B
   Both Statement I and Statement II are incorrect.
3. C
   Statement I is correct but Statement II is incorrect.
4. D
   Statement I is incorrect but Statement II is correct.
