Q. The position vector of center of mass is given by

द्रव्यमान के केंद्र की स्थिति वेक्टर द्वारा दी गई है

A
m1r1 + m2r2 / (m1 + m2)
एम1आर1 + एम2आर2 / (एम1 + एम2)
B
(m1 + m2) / (r1 + r2)
(एम1 + एम2) / (आर1 + आर2)
C
m1r2 + m2r1
एम1आर2 + एम2आर1
D
r1 + r2 / 2
आर1 + आर2/2

Explanation

For a system of two particles, the center of mass position vector RCM\vec{R}_{CM} is calculated as:

RCM=m1r1+m2r2m1+m2\vec{R}_{CM} = \frac{m_1 \vec{r}_1 + m_2 \vec{r}_2}{m_1 + m_2}

This formula represents the weighted average position of the masses.
