Q: An object of mass 10kg is placed at the height of 6 meter from the ground. Calculate the potential energy stored in it. (g=9.8 m/sec²)
  • A. 578 J
  • B. 588 J
  • C. 578 W
  • D. 588W
Correct Answer: Option B - Potential energy = m×g×h here, m = 10 kg, h = 6 m, g = 9.8 m/s² = 10×9.8×6 =98×6 = 588J
B. Potential energy = m×g×h here, m = 10 kg, h = 6 m, g = 9.8 m/s² = 10×9.8×6 =98×6 = 588J

Explanations:

Potential energy = m×g×h here, m = 10 kg, h = 6 m, g = 9.8 m/s² = 10×9.8×6 =98×6 = 588J
