Suppose the spring is stretched a distance x metres from its equilibrium position. Then suppose the spring is stretched an additional distance dx from there: STRETCHED STRETCHED dx FURTHER mm- dx Which of the following expressions is a good approximation for the amount of work required to stretch the spring the additional distance of dx? (Here, we're thinking about dx as being incredibly small.) Oa. W 20x dx O b. W x2 O C. W 2dx O d. W 0.1x dx
