Question 1
What is the formula for finding the Centre of Mass of two particles?
- X_cm = (m₁x₁ + m₂x₂) / (m₁ + m₂)
- X_cm = (m₁ + m₂) / (x₁ + x₂)
- X_cm = (m₁x₂ – m₂x₁) / (m₁ + m₂)
💡 Hint: Recall the terms m₁ and m₂ as indicators of mass.
Question 2
True or False: The Centre of Mass of a uniform object is located at its geometric center.
- True
- False
💡 Hint: Consider a perfect shape like a circle.
