Q: When an object of 11kg is placed at a height of 7m from the ground, how much energy it will contained?
  • A. 528J
  • B. 520J
  • C. 588J
  • D. 754.6J
Correct Answer: Option D - Here, m = 11 kg, h = 7 m g = 9.8 m/s ² P.E = m × g × h = 11 × 7 × 9.8 = 77 × 9.8 = 754.6 J
D. Here, m = 11 kg, h = 7 m g = 9.8 m/s ² P.E = m × g × h = 11 × 7 × 9.8 = 77 × 9.8 = 754.6 J

Explanations:

Here, m = 11 kg, h = 7 m g = 9.8 m/s ² P.E = m × g × h = 11 × 7 × 9.8 = 77 × 9.8 = 754.6 J
