A particle moves along the loop A–B–C–D–A while a conservative force acts on it. Work done by the force along the various sections of the path are `-W_(AtoB)=-50 J, W_(BtoC) =25 J, W_(CtoD)=60 J`. Assume that potential energy of the particle is zero at A. Write the potential energy of particle when it is at B and D.

Answer

`U_(B)=50 J; U_(D)=-35 J`
