Q: An object of mass 12kg is placed at a certain height from the ground. If the potential energy of the object is 600J, find the height from the ground of the object?
  • A. -5m
  • B. 5ms⁻²
  • C. 5m
  • D. 5ms²
Correct Answer: Option C - Potential energy = m×g×h Here, P =600 J, m =12kg, h = ? and g = 10 m/s² 600 = 12 ×10 × h h = 600/120 = 5 m
C. Potential energy = m×g×h Here, P =600 J, m =12kg, h = ? and g = 10 m/s² 600 = 12 ×10 × h h = 600/120 = 5 m

Explanations:

Potential energy = m×g×h Here, P =600 J, m =12kg, h = ? and g = 10 m/s² 600 = 12 ×10 × h h = 600/120 = 5 m
