Question

The relationship between the force F and position x of a body is as shown in the figure. The work done in displacing the body from x = 1 m to x = 5 m will be, 30 J, 15 J, 25 J, 20 J

MARKS App · Accepted Answer

Work done = force x displacement = area of ABNM + area of CDEN + area of EFGH + area of HIJ - area of OAM = -1 2 × 1 × 1 0 + 1 × 5 × 5 + 1 2 × 1 × 1 0 = 2 0 J
