A force of 200 N moves a body througha distance of 2 m in the direction offorce. Calculate the work done by theforce.​

Answer»

Given :-

Force applied on the body = 200 N

Distance in the DIRECTION of force = 2 m

To Find :-

The work done by the force.

Analysis :-

Here we are given with the distance and and the force applied on the body.

In order to find the work done by the force substitute the given values such that work done is equal to the force MULTIPLIED by the displacement.

Solution :-

We know that,

  • f = Force
  • s = Displacement
  • w = Work done

Using the FORMULA,

\underline{\boxed{\sf Work \ done= Force \ applied \times Displacement}}

Given that,

Force (f) = 200 N

Displacement (s) = 2 m

Substituting their values,

⇒ w = fs

⇒ w = 200 × 2

⇒ w = 400 J

Therefore, he work done by the  force is 400 J.
