Answer 1

${ \huge{ \sf{ \underline{ \underline { \red{Answer}}}}}}$

❥︎Gravitational potential energy is the energy an object has due to its position above Earth, energy due to its height. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.

❥︎We know,

Let mass be m

Ratio = P.E of A/P.E of B

          = mgh/mg2h

          = 1:2

Answer 2

Answer:

gravitational potential= amount of work done on an object to raise it to height (h) above the ground .

formula=mgh

M1=M=M2 (EQUAL MASSES)

g= accelaration due to gravity

H1 =h

H2= 2(H1)= 2h

gravitational energy of 1st object =mgh =M x g x h ------(1)

gravitational energyof 2nd = M x g x 2h -------(2)

(1)/(2)=. M x g x h/ M x g 2h

=h/2h

=1/2. or 1:2
