How does doubling the height of a cylinder affect its gpe?

Doubling the height of a cylinder will increase its gravitational potential energy (GPE) if the mass remains constant. GPE is calculated using the formula ( \text{GPE} = mgh ), where ( m ) is mass, ( g ) is the acceleration due to gravity, and ( h ) is height. Therefore, if the height ( h ) is doubled, the GPE will also double, assuming mass and gravitational acceleration remain unchanged.
