Question

When two different stones of masses 1kg and 2kg are taken to the same heights, then:

• A. The potential energy of the stone of mass 1 kg is more than that of the 2 kg stone.
• B. The potential energy of the stone of mass 2 kg is more than that of the 1 kg stone.
• C. The potential energy of both the stones would be the same.
• D. Cannot be judged with the given information.

Answer 1

The correct option is B

The potential energy of the stone of mass 2 kg is more than that of the 1 kg stone.

Potential energy is mathematically represented by the formula,
$\text{P.E. = m}\times g\times h$
where m is the mass,
g is acceleration due to gravity and
h is the height in meters.
Potential energy is directly proportional to the mass of the object. Therefore, the stone of mass 2kg would have higher potential energy than a stone of mass 1kg.
