NEET2019PhysicsWork, Power and EnergyActual
A man applying force of 20 N on an object at an angle of 60^ from the horizontal. If object moved by 20 m in horizontal direction, then work done by the force on the object is
Options
- A300 J
- B400 J
- C100 J
- D200 J
Correct answer
D. 200 J
Step-by-step solution
Given, force, f =20 ~N , angle =60^ and displacement ( s )=20 ~m , Work done by the force aligned W & = fs =20 20 60^ =20 20 1 2 & =200 ~J aligned
