Dear Student!
Potential energy due to gravitation is given as, PE = mgh, where m is the mass, g acceleration due to gravity and h is the height.
m = 200 kg, g = 9.8 m/s2, PE = 9800 J, h = ?
Now, 200 × 9.8 × h = 9800 J
⇒ h = 5 m
Thus, the height t owhich the body is raised will be 5 m.
Hope it is clear!
Best wishes!!
