Question

four equal masses 'm' lie at the corners of a triangle of with a and length be. the CM of the system is at a) (a,b). b) (a/2,b/2). c) (b/2,a/2). d) (b,a).​

Answer 1

Answer:(a/2,b/2)

Explanation:

Answer 2

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.
