Answer:
W = 0 J
Explanation:
It is given that,
Weight of the crate, W = 100 N
Distance moved by the crate, d = 1.5 m
Let W is the work done to hold the crate 1.5 m above the ground in this way. It is given by the product of force and the displacement. Its formula is given by :

Here,
as it is lifted vertically
W = 0
So, the work done to hold the crate is 0. Hence, this is the required solution.
