A body of mass 20 kg is held at a height of 2 m above the ground means there is no displacement because of which there is no change in its potential energy. Hence work done is zero.

Explanation:
Work done to lift an object at a height above earth surface is given by formula,
W=mgh,
where
m=20 kg = mass of object,
h=2 m = height
On putting values, we get
W=20×10×2=400 Joule
