Question

The gravitational potential energy of a 2 kg object at a height of 5 m above the surface of the Earth is?

• A. 100 J
• B. 150 J
• C. 50 J
• D. 25 J

Hint:

Gravitational potential energy depends on the height of the object above the Earth's surface and is directly proportional to both mass and height.

Answer 1

The Correct Option is A

The formula for gravitational potential energy (GPE) is \( U = mgh \). Given: \( m = 2 \, \text{kg} \), \( g = 9.8 \, \text{m/s}^2 \), and \( h = 5 \, \text{m} \). The calculated potential energy is \( U = 2 \times 9.8 \times 5 = 100 \, \text{J} \). Therefore, the gravitational potential energy is \( 100 \, \text{J} \).
