Correct option is C)

Step 1: Potential Energy

Gravitational Potential energy is given by PE = mgh

Where, h= height, m= mass, g= acceleration due to gravity

Step 2: Ratio of potential energy

Both the bodies have same mass.

Potential energy of bodies:

∴ (PE)

1

=mgh and (PE)

2

=mg(2h)

⇒ (PE)

1

:(PE)

2

=1:2
