Work done by the conservative force on a system is equal to :

Options

A. (a) The change in kinetic energy of the system
B. (b) The change in potential energy of the system
C. (c) The change in total mechanical energy of the system
D. (d) None of the above

Answer

B

Explanation

We know that `dU=-dW`
where `dU` is the change in potential energy
and `dW` is the work done by conservative energy
Hence, work done by conservative forces on a system is equal to the negative of the change in potential energy.
