Answer:
yes it will be 1:2
Step-by-step explanation:
gravitational potential energy is equal to
= mgh[m=mass,g=acceleration due to gravity,h=height at which object is placed]
in the given question
masses are same and acceleration is constant i.e.9.8m/s sq.
height of first body=h
height of second body=2h
ratio
P.E of 1st mgh
-------------- = ---------
P.E of 2nd mg(2h )
mgh will cancel out and the answer will be 1:2
plz plz mark as brainliest........
