Question

what happens to the potential energy of a body when its height is doubled?

Answer 1

P.E =mgh
Ih h=2h
then
P.E" =mg(2h)

Or
P.E'=2mgh
mgh=P.E
So
P.E'=2P.E
That is if we double height then potential energy is also doubled

Answer 2

Hey mate here is your answer




Typically, the ground is considered to be a position of zero height. ... Since the gravitational potential energy of an object is directly proportional to its height above the zero position, adoubling of the height will result in adoubling of the gravitational potential energy.
