Given,
Mass of object m=10kg.
Height h=6m.
Acceleration due to gravity g=9.8m/s
2
Potential Energy of object P.E=m×g×h
⇒mgh=10×9.8×6=98×6
=588J
Energy possessed by the object is 588Joule.

Answer:
Given:
Mass=6kg
Height1- 20cm - 0.2 m
Height2-2m
Less force be x
Explanation:
PE -mgh
PE 1- 0.2x x 6=1.8x
PE2=2x x 6=18x
PE2-PE1=18x-1.8x=16.2x
Since we assumed the force as x we will remove x so the final answer is
16.2
