NTA Abhyas JEE Main2020PhysicsWork, Power and EnergyPractice
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
Options
- A30   J
- B15   J
- C25   J
- D20   J
Correct answer
D. 20   J
Step-by-step solution
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
