NEET2011PhysicsWork, Power and EnergyActual
Force F on a particle moving in a straight line varies with distance d as shown in the figure. The work done on the particle during its displacement of 12 ~m is
Options
- A21 ~J
- B26 ~J
- C13 ~J
- D18 ~J
Correct answer
C. 13 ~J
Step-by-step solution
Work done = Area under (F-x) graph aligned & =2 (7-3)+ 1 2 2 (12-7) & =8+ 1 2 10 & =8+5=13 ~J aligned
