A pair of bullocks exerts a force of `140 N` on a plough. The field being ploughed is `15 m` long. How much work is done in ploughing the length of the field?

Text Solution

Verified by Experts

The correct Answer is:
Work done by the bullocks is 2100 J.
Here, Force `(F)=140N`,
displacement `(s)=15m, W=?`
`W=Fxxs`
`=140Nxx15m=2100Nm=2100J`
