Three particles of mass 1kg, 2kg and 3kg are placed at the corners A, B and C respectively of an equilateral triangle ABC of edge 1m. How do I find the distance of their centre of mass from A?
The mass of the particles are 1kg, 2kg, and 3kg, and they are placed at the corners A, B, and C respectively of an equilateral triangle ABC of edge 1m.
Okay. To find the center of mass, we need to calculate the weighted average of the position of the particles, where the weights are their masses. Do you know the formula for the center of mass of a system of particles?
