A body of mass 500 g is taken up an inlclined plane of length 10 m and height 5 m, and then released to slide down to the bottom. The coefficient of friction between the body and the plane is 0.1. What is the amount of work done in the round trip ?
detailed solution
Correct option is C
here work done is only due to friction in both the ways as it is a noncoservative force w=μmgcosθ l x2 here sinθ=hl=510=0.5 θ=300 w=0.1x0.5x10x10x32x2 = 53Talk to our academic expert!
