Answer:

Work done 10 Joule

Explanation:

Force applied = 20N

Displacement of object = 50cm in direction of force

Need to find:

Work done =?

Solution :

Displacement = 50cm = 0.5m

Now we know

Work done = Force × Displacement

⟹ Work done = 20N × 0.5 m

⟹ Work done = 10 Joules

━━━━━━━━━━━━━━━━━━

Knowledge cell:

Work done by a constant force is equal to the scales product of the force applied and displacement of the point of application.

Work = Force × Component of force along displacement

Is represented by : W = F.d. cos \thetaθ

Work is a scaler quantity

Answer:

Explanation:

Force applied = 20N

Displacement of object = 50cm in direction of force  

Work done =?

Displacement = 50cm = 0.5m (given)

 

Work done = Force × Displacement

Work done = 20N × 0.5 m

Work done = 10 Joules
