A box is pulled with a force of 25 N to produce a displacement of 15 m. If the angle between the force and displacement is `30^(@)`. Find the work done by the force ?

Text Solution

Verified by Experts

Force,F=25
Displacement , `dr=15m`
`"Angle between" F and dr,theta=30^(@)`
`"work done"W=F and drcostheta`
`W=25xx15xxcos30^(@)=25xx15xxsqrt3/2`
`W=324.76J`
