Consider the following statements and choose the correct option
I) Position vector of centre of mass of two particles of equal mass is equal to the position vector of either particle
II) Centre of mass is always at the midpoint of the line joining two particles
III) Centre of mass of a body can lie where there is no mass

View answer and explanation

Correct option: C

II and III

Option C (II and III) is correct because the center of mass is always at the midpoint of the line joining two particles of equal mass and can lie where there is no mass.
