Answer : Height, s = 4 m

Explanation :

It is given that,

Work done, W = 40 J

Force applied on the box from the floor to a shelf,
$F=10\ N$

We know that the work done is defined as the force applied on an object to produce a displacement on it.

Mathematically, it is written as :

W=F* s

s is the height of the shelf

s=(W)/(F)

$s=(40\ J)/(10\ N)$

$s=4\ m$

So, the height of the shelf is 4 m.

Hence, this is the required solution.
