Where is the center of mass of a two particle system?
• The centre of mass of a body or a system is its balancing point. The centre of mass of a two- particle system always lies on the line joining the two particles and is somewhere in between the particles.
What is the motion of a system of particles?
We shall consider the motion of a system as a whole. The main concept here would be the centre of mass of a system of particles. We will discuss its motion and its usefulness as per the CBSE syllabus. Students can now download the authentic answers of the NCERT Solutions for Class 11 Physics from the link available here. Q1.
How is the centre of mass defined in a rigid body?
• A rigid body is a body with a perfectly definite and unchanging shape. The distances between all pairs of particles of such a body do not change. For a system of particles, the centre of mass is defined as that point where the entire mass of the system is imagined to be concentrated, for consideration of its translational motion.
How is the position of the centre of mass unchanged in rotatory motion?
ROTATORY MOTION 1 The position of centre of mass remains unchanged in pure rotatory motion. ... 2 The position of centre of mass of a body is independent of the choice of coordinate system. 3 If we take the centre of mass at the origin, then the sum of the moments of the masses at of the system about the origin is zero.
