NEET2009PhysicsWork, Power and EnergyActual
A force F acting on an object varies with distance x as shown in the figure. The force is in N and x in m . The work done by the force in moving the object from x=0 to x=6 ~m is
Options
- A13.5 ~J
- B10 ~J
- C15 ~J
- D20 ~J
Correct answer
A. 13.5 ~J
Step-by-step solution
Work done by force = Area under force- displacement graph. =3 3+ 1 2 3 3=9+4.5=13.5 ~J
