Question

Find the work done by the force f=2i-3j+k when its point of application

Answer 1

Work done by force acting on a object/body can be described as formula below

W=F∗sW=F∗s

W= work done

F= force acting

s= displacement of the object/body

So work is force multiplied by displacement

But when the force and displacement or given in vector form we use dot product or scalar product as the work done is a scalar[1] , like below

W=F⃗ ⋅s⃗ W=F→⋅s→

Here the force the force is already give as F⃗ =2i^−3j^+k^F→=2i^−3j^+k^
