Initially two stable particles \( \mathrm{x} \) and \( \mathrm{y} \) start moving
\( \mathrm{P} \) towards each other under mutual attraction. If at

W. one time the velocities of \( \mathrm{x} \) and \( \mathrm{y} \) are \( \mathrm{V} \) and \( 2 \mathrm{~V} \) respectively, what will be the velocity of centre of mass of the system?
(1) \( \mathrm{V} \)
(2) Zero
(3) \( \frac{\mathrm{V}}{3} \)
(4) \( \frac{\mathrm{V}}{5} \)
