Questions
The work done by the force = , where A is a constant and x and y are in meters around the path shown is:
detailed solution
Correct option is D
∫F. dx = ∫A(y2i^+2x2j^)(dxi^+dyj^) = A∫(y2dx+2x2dy)WOA = 0+0, WAB = A[0+2d2d]WBC = A[d2(-d)+0], WCD = A[0+0]W = 0 + 2Ad3-Ad3+0 = Ad3Similar Questions
