CBSE Class 11-science - Centre of Mass Videos
Systems of Particles and Rotational Motion
This video explains the nature of a rigid body, the centre of mass, the motion of the centre of mass and the location of the centre of mass.
- A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
- A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is?
