As per your syllabus, eqn 6.1, the centre of mass of two particles m₁ at x₁ and m₂ at x₂ is which?
A(m₁ + m₂)/(x₁ + x₂) ratio
B(m₁x₁ − m₂x₂)/(m₁ + m₂)
C(m₁x₁ + m₂x₂)/(m₁ + m₂)
D(x₁ + x₂)/2 (any masses)
Answer & Solution
Correct answer: C. (m₁x₁ + m₂x₂)/(m₁ + m₂)
Your syllabus: X = Σ m_i x_i / Σ m_i.
For equal masses it reduces to the midpoint.
