A box is dragged along a horizontal floor by a rope which makes an angle of 60° with the horizontal. How much work is done if the tension in the rope is 150 N and the box is dragged through a distance of 10 m.

750 J

1500 J

`750sqrt3 J`

None of these

Text Solution

Verified by Experts

The correct Answer is:

Work done W=F s cos `theta`
=`150xx10xxcos60^(@)=1500xx1/2=750J`.
