Question

How much force is applied on the body when 150 joule of work is done in displacing the body through a distance of 10m in the direction of force?

Answer 1

W = F x S 
F = w/s
   = 150/10
   = 15 N

Answer 2

Given,

Work done in displacing a body through a distance = 150 J

Total distance displaced = 10 m

To find,

The force applied to the body.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

Work done (W)

= Force applied (F) x total displacement (d)

=> Force applied (F) = Work done (W) / total displacement (d)

Now, according to the question;

The force applied to the body

= Work done (W) / total displacement (d)

= 150 J / 10 m

= 15 N

Hence, a total of 15 N force is applied to the body.
