Question

A circular plate of radius $R$ is kept in contact with square plate of edge $2R$ as shown in figure. The density of the material and the thickness are same everywhere. The CM of the composite system will be:

• A. at the point of contact
• B. inside the circular plate
• C. inside the square plate
• D. outside the system

Answer 1

The correct option is A at the point of contact

A circular plate of radius RR is kept in contact with square plate of edge 2R2R as shown in figure. The density of the material and the thickness are same everywhere. The CM of the composite system will be at the point of contact.

so the option is A.
