Question

What is Centre of Mass of Two Particle System?

Answer

Centre of Mass of Two Particle System - Consider the two particles system in which two masses m1 and m2 are separated by a distance d. The Centre of mass (CM) divides internally the line joining two particle (or masses) in inverse ratio of their masses. PR = m2d/m1 + m2 and QR = m1d/m1 + m2
