A body is moved up along a rough inclined plane of length 10m and height 5m and then allowed to slide down to the bottom again. If the mass of a body is 10kg and the coefficient of friction is 1/√3, what is net work done round the trip by the frictional force? (g=10m/s^2).
(A) -1000J
(B) 1000J
(C) 500J
(D) 2000J
