TS EAMCET · Physics · Center of Mass Momentum and Collision
The masses and positions (in rectangular coordinates) of four particles are as follows : \(1 \mathrm{~kg}\) at \((a, a), 2 \mathrm{~kg}\) at \((-a, a), 3 \mathrm{~kg}\) at \((a, a)\) and \(4 \mathrm{~kg}\) at \((a, a)\). The position vector of the centre of mass of the system of four particles is
- A \(-4 a \hat{\mathbf{i}}\)
- B \(-4 a \hat{\mathbf{i}}-4 \hat{\mathbf{j}}\)
