Answer...
Given height = 20 cm = 0.2 m
Formula of work done →
W = F x s = m x g x h
W = m x 10 x 0.2 ( considering mass = m)
W = 2m Joules

Heya!
Here is ur answer...
Given that,
Height(h) = 20 cm = 20/100 = 1/5
Mass(m) = m
Acceleration due to gravity(g) = 10 m/s²
Work done = mgh
W = m× 10 × 1/5
W = m × 2
W = 2m joule.
Therefore, Work done = 2m joule
Hope it helps u..
