Question

Four equal masses ‘m’ lie at the corners of a rectangle of width a and length b. the CM of the system is at

Answer 1

Thus the centre of mass of the system lies at the centre of the triangle.

Explanation:

• Since the masses are equal and all the masses are arranged symmetric to diagonal point.
• Because all the masses are equal in distance from the diagonal mid point of the triangle.
• Also from the center of the rectangle hence the center of mass lies on the center of the rectangle.
• Thus the centre of mass of the system lies at the centre of the triangle.
