here is an object (mass m) at rest on the bottom of the rough inclined surface (B angle with the ground). You decide to bring that upward d distance on an inclined surface y dragging the object by using a rope attached to the object with force F. Which of the following expressions will be the correct one about work done from forces acting on he object? Work done from Fgis – mgdsinß Work done from Fis Fd Work done from FN is mgcosß Work done from Ffis negative Work done from Fois mgdsinß Work done from Fis Fd O Work done from FNis mgcosß Work done from Ffis negative Work done from Fgis – mgdsinß Work done from Fis Fd O Work done from FN is zero Work done from Ffis negative Work done from Fgis – mgdcosß Work done from Fis Fd O Work done from FN is mgsinß Work done from Fis negative
