Question

For a system of two particles with different masses, where is the centre of mass located?

Options

• At the midpoint between them

• Closer to the lighter mass

• Closer to the heavier mass

Answer 1

Closer to the heavier mass

Explanation:

The centre of mass divides the distance between two particles in an inverse ratio of their masses, meaning it is closer to the heavier mass.
