Question

Write an expression for the location of centre of mass of a
two particle system.​

Answer 1

Answer:

For a system of two particles with equal masses, CoM is the point that lies exactly in the middle of both. From the equation above we get the centre of mass of two particles with equal masses. From the above equation, it is clear that the CoM of two particles lies in the midway of both.

Answer 2

Answer:

x(centre of mass)= (m1x1 + m2x2) / m1 + m2

y(centre of mass) = (m1y1 + m2y2) / m1 + m2
