STANDARD Physics System Of Particles And Rotational Motion Class 11 Questions

The centre of mass of a body

Three particles of masses 1 kg, \( \frac{3}{2} \) kg, and 2 kg are located at the vertices of an equilateral triangle of side a. The x, y coordinates of the centre of mass are

Statement-1: If there is no external torque on a body about its centre of mass, then the velocity of the centre of mass remains constant. Statement-2: The linear momentum of an isolated system remains constant.
