Hi
Work done = force × distance
= mg ×h
15 ×10×1.5
= 15 × 15
= 225 joule

can you explain how you did
I used formula of work .then minimum force needed to move up will be equal to downward force and downward force is weight which is mass × acceleration due to gravity

Heya folk !!
Here's the answer you are looking for
The potential energy of a body = work done by it.
So, W = U = mgh
Here, m = 15kg
g = 10m/s²
and h = 1.5m
So,
W = U = mgh
= 15 × 10 × 1.5
= 225J
