In which of the following cases the, potential energy is defined?

1.	In which of the following cases the, potential energy is defined?
Answer» both conservative and non-conservative forces conservative FORCE only non-conservative force only Neither conservative nor-conservative forces Solution :(b) Potential energy is only ASSOCIATED with conservative forces. Force, `F=-((del U)/(del x)hati+(del U)/(del y)hat j+(del U)/(del z)hat K)` where, F =Conservative force `((del U)/(del x)hati+(del U)/(dely)hatj+(delU)/(delz)HATK)="Partial derivative of potential energy"` w.r.t.x,y and respectively.
