Find the work done if a particle moves from position `r_(1)="to a position"vecr_(1)=(3hati+2hatj-6hatk) "to position "vecr_(2)=(14hati+13hatj-9hatk)"under the effect of force " vecF=(4hati+hatj+3hatk)N`

Text Solution

Verified by Experts

`vecr=vecr_(2)-vecr(1)11hati+11hatj-3hatk`
`vecF=(4hati+hatj=3hatk)N`
`W=vecF*vecr=46J`
