Question

(c) A body of mass 10 kilogram is taken from a height of 3metres to 6 metres, find increase
in potential energy of the body.(Take ge 10ms)​

Answer 1

Answer:

potential energy at 3 metre =mgh1=10×10×3=300J

potential energy at 6 meters =mgh2=10×10×6=600J

difference =600-300=300J

increase in energy =300J
