Q103 / 200 · NEET 2011 (Screening) · Physics

The potential energy of a system increase if work is done

  • Correct answer
    A
    by the system against a conservative force
  • B
    by the system against a nonconservative force
  • C
    upon the system by a conservative force
  • D
    upon the system by a nonconservative force

Solution

The potential energy of a system increases if work is done by the system against a conservative force. $$ -\Delta U=W_{\text {conservative face }} $$

Hence, the correct answer is option: 'A'.
