Question :
Three spheres of equal masses are arranged as shown in the figure. Find the coordinates of the centre of mass the system.
Solution :
❒ Position vector of centre of mass is given by
Where, r₁, r₂, ... , rₙ denotes position vectors of point masses m₁, m₂, ... , mₙ respectively.
Sphere A : (x₁ | y₁) = (0 | 0)
Sphere B : (x₂ | y₂) = (a/2 | 0)
Sphere C : (x₃ | y₃) = (0 | 2a)
Assuming all three spheres as point masses,
❒ x - coordinate of COM :
❒ y - coordinate of COM :
Coordinates of COM :
