The velocities of three particles of masses

20 \mathrm{~g}

30 \mathrm{~g}

and

50 \mathrm{~g}

are

10 \hat{{i}}, 10 \hat{{j}}

and

10 \hat{{k}}

respectively. The velocity of the centre of mass of the three particles is

View answer and explanation

Correct option: A

2 \hat{i}+3 \hat{j}+5 \hat{k}

Option A (

2 \hat{i}+3 \hat{j}+5 \hat{k}

) is correct because it is the result of applying the center of mass velocity formula.
