The center of mass is located 2.5 m from 3 kg point mass, (and 1.5 m from the 5 kg point mass) on X-axis. This result shows that the center of mass is located closer to larger mass. If the origin is shifted to the center of mass, then the principle of moments holds good. m 1 x 1 =m 2 x 2; 3x2.5=5x1.5;7.5=7.5

Question 1 (**) Four particles A, B, C and D have masses 1kg, 2kg, 3kg and 4kg, respectively. The respective coordinates of the particles A, B, C and D are (2,3), (4,0), (−1,5) and (− −3, 4). a) Find the coordinates of the centre of mass of this system of four particles.
Answer. We know that center of mass will move under the action of force of gravity So $\mathbf{r_c}=\mathbf{v_c}t+\frac{1}{2}\mathbf{g}t^2$ Or $\mathbf{r_c}=\frac{m_1\mathbf{v_1}+m_2\mathbf{v_2}}{m_1+m_2}t+\frac{1}{2}\mathbf{g}t^2$ Multiple Choice Questions Question 23 Two masses m 1 and m 2 separated by thin rod of length L.
