Question

If m1 and m2 are the masses constituting the rigid body, bound by some

internal forces so that the distance between the masses remain constant

then

I) Define centre of mass.

II) Derive expression for position vector of centre of mass.​

Answer 1

Answer:

Answer

The forces of attraction between the particles are the internal forces. Therefore, the center of mass of the system will have no acceleration. The particles move, but the center of mass will continue to be at the same place. At the time of collision, the two particles are at one place and the center of mass will also be at that place. As the center of mass does not move, the collision will take place at the center of mass.

Answer 2

Answer:

in physics the centre of mass of a distribution of mass in space in the unique point where the weighted relative position of the distributed mass sums to zero this is the point of which a force may be applied to cause a linear equations acceleration without an angular acceleration
