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

Options

A. the change in kinetic energy of system
B. the change in potential energy of system
C. the change in total machanical energy of system
D. None of the above

Answer

B

Explanation

We know that `dU = - dW`
`where dW = `work done by conservative force Hence work done by the conservative force is equal to the negative of the change in potential energy
