Which of the following statements are incorrect about centre of mass?
I) Centre of mass can coincide with geometrical centre of a body
II) Centre of mass of a system of two particles does not always lie on the line joining the particles
III) Centre of mass should always lie on the body

View answer and explanation

Correct option: A

II and III

Option A (II and III) is correct because the center of mass can coincide with the geometrical center and must lie on the line joining two particles, and it doesn't always have to be on the body.
