Detailed Solution

When two objects A and B of equal masses are kept at heights of

2 h

and

5 h

respectively, the ratio of their potential energies will be

4 : 5

Let mass of object A is

m_{1}

and that of object B be

m_{2}

.
It is given that

m_{1} = 2 m_{2}

We also know that heights of A and B are

2 h

and

5 h

respectively.
Acceleration due to gravity for both objects is

g .

Mathematically, Potential energy

(P)

can be expressed as

P = mgh

Where

m

is the mass of the object,

g

is the acceleration due to gravity and

h

is the height of the object.
Thus, the ratio of potential energy

P E_{1} : P E_{2}

of given objects is,

\frac{2 mg (2 h)}{mg (5 h)}

\Rightarrow \frac{P E_{1}}{P E_{2}} = \frac{4}{5}

Hence, the ratio of potential energies is

4 : 5
