Q: Calculate the potential energy obtained by a 20kg hammer, when it is raised to a height of 10m?
  • A. 3000Pa
  • B. 2000J
  • C. 3000W
  • D. 3000N
Correct Answer: Option B - Potential energy = m×g×h Here, P.E. =?, m =20 kg, h = 10 m and g = 10 m/s² P.E. = 20 ×10 × 10 = 2000J
B. Potential energy = m×g×h Here, P.E. =?, m =20 kg, h = 10 m and g = 10 m/s² P.E. = 20 ×10 × 10 = 2000J

Explanations:

Potential energy = m×g×h Here, P.E. =?, m =20 kg, h = 10 m and g = 10 m/s² P.E. = 20 ×10 × 10 = 2000J
