Question

Three bodies equal masses are placed at (0,0), (a,0) and (a\2),a√3\2)​. find out the coordinates of centre of mass

Answer 1

Answer:

(a/2 , a/2√3)

Explanation:

COM= (∑m₁x₁/∑m₁ , ∑m₁y₁/∑m₁ )

as masses are equal

COM= (∑x₁/3 , ∑y₁/3 )

COM=( (0+a+a/2 )/ 3 , ( 0+0+a√3/2)/3)

        = (a/2 , a/2√3)
