Three particles of masses \(100~\text{g}\), \(150~\text{g}\), and \(200~\text{g}\) respectively are placed at the vertices of an equilateral triangle of a side \(0.5~\text{m}\) long. What is the position of the centre of mass of three particles?
1. \(\left(\dfrac{5}{18} , \dfrac{1}{3 \sqrt{3}}\right) \)
Position of centre of mass of a triangular lamina as shown in the figure is:
