Answer : Work done, W = 9 J
Explanation :
It is given that,
Force used to lift the box, [tex]F=10\ N[/tex]
Distance, [tex]d=0.9\ m[/tex]
Work done is equal product of the force and the distance travelled by it.
Mathematically, it is given as :
[tex]W=F\times d[/tex]
[tex]W=10\ N\times 0.9\ m[/tex]
[tex]W=9\ J[/tex]
The work done to lift a box is 9 J.
Hence, this is the required solution.
