A particle is taken from point A to point B under the influence of a force field. Now it is taken back from B to A and it is observed that the work done in taking the particle from A to B is not equal to the work done in taking it from B to A. If `W_(nc)` and `W_c` are the work done by non-conservative and conservative forces present in the system, respectively, `DeltaU` is the change in potential energy and `Deltak` is the change in kinetic energy, then

A

`W_(nc) - Delta U = Delta D`

B

`W_(c) = - Delta U`

C

`W_(nc) + W_(c) = Delta k`

D

`W_(nc) - Delta U = - Delta k`
