Position vector of centre of mass of two particles system is given by:
View answer and explanation
Correct option: D
R⃗=m1r⃗1+m2r⃗2m1+m2\vec{R}=\frac{m_1 \vec{r}_1+m_2 \vec{r}_2}{m_1+m_2}
Option D (R⃗=m1r⃗1+m2r⃗2m1+m2\vec{R}=\frac{m_1 \vec{r}_1+m_2 \vec{r}_2}{m_1+m_2}) is correct because it represents the formula for the position vector of the center of mass of a two-particle system.
