How many joules of work is done on an object when a force of 10 N pushes it to a distance of 10 m?

In this case,Work done = Force x Distance ,So, Distance = Work done/force = 720/40 = 15 metres.*Note : If the force tends to slow the object down, then Workdone = -(Force x Distance )

Text Solution

`20 J``100 J``15 J``10 J`

Answer : D

Solution : The work done is calculated by using the formula : <br> `W = F xx s` <br> Here, Force, F = 10 N <br> And, Distance, s = 1 m <br> So, Work done, `W = 10 xx 1 J` <br> = 10 J <br> Thus, the work done is 10 joules.
