Q: When an object of 10kg is placed at a height of 7m from the ground, how much energy it will contained -

Correct Answer: Option B - Here, m = 10 kg, h = 7 m g = 9.8 m/s ² PE = mgh E = 10 × 9.8 × 7 = 686 J

B. Here, m = 10 kg, h = 7 m g = 9.8 m/s ² PE = mgh E = 10 × 9.8 × 7 = 686 J

Explanations:

Here, m = 10 kg, h = 7 m g = 9.8 m/s ² PE = mgh E = 10 × 9.8 × 7 = 686 J
