Question

On applying a force of 8 kg watt to a body it displaces 4m in the direction of force . Find the amount of work done

Answer 1

work done = force x displacement
W= 8x4
W=32 joules

Answer 2

Given :

Force applied , F = 8 N .

Displacement , d = 4 m ( in the direction of force ) .

To Find :

The amount of work done .

Solution :

We know , work done is given by :

$W=Fd\ cos\ \theta$

It is given that body is displace in the direction of force .

So , $\theta=0^{\circ}$

Therefore , $cos\ 0^{\circ}=1$

Putting all these values in above equation .

We get :

$W=8\times 4\times 1\\\\W=32\ J$

Hence , this is the required solution .
