Which of the following statements regarding centre of mass is NOT true?
  1. For two particles of equal mass, the centre of mass lies exactly midway between them
  2. For three non-linear particles of equal mass, the centre of mass coincides with the centroid of the triangle formed by the particles
  3. When the total external force on a system is zero, the velocity of the centre of mass of the system remains constant.
  4. For two particles of different masses, the centre of mass of the particles is nearer to the particle of lesser mass.
