What is the mechanical work done by the cantilever when the extension increases from 10 nm to 15 nm? 2.00 × 10-22 J 4.70 × 10-20 J 2.50 × 10-19 J 5.00 × 10-18 J correct answers This question requires you to apply the graphical method of calculating the work done by a variable force, namely the elastic force, W = ksx2/2. Mechanical work by an elastic force is W = ksx2/2 = Fx/2. Graphically, it is the area under the force-extension graph between the corresponding data points. From Figure...
