Question

If the two particles of masseam1 and m2 are d distance apart then what will be the position of their centre of mass from m2

Answer 1

Given,
Masses = m1 , m2
Distance of separation = d.

We know that,
Distance of centre of mass from the second body = Mass of First body * Distance of Separation / Sum of Masses.

Let r2 be the position of centre of mass from the second body.

r2 = m1 * d / m1 + m2 .

Hope helped!
