Physics - W.E.P. Question with Solution | TestHub

For a conservative force, the work done ($W_c$) is equal to the negative change in potential energy, or the initial potential energy minus the final potential energy.$$W_c=U_{\text{initial}}-U_{\text{final}}=U_A-U_B$$ Given $U_A=10\text{J}$ and $U_B=4\text{J}$.$$W_c=10\text{J}-4\text{J}=6\text{J}$$
