Three particles of masses `1kg`, `2kg` and `3kg` are placed at the corners A, B and C respectively of an equilateral triangle ABC of edge `1m`. Find the distance of their centre of mass from A.

A

`sqrt(6) m`

B

`sqrt(2)m`

C

`1/(sqrt(2)m`

D

`2m`

Text Solution

Verified by Experts

The correct Answer is:
B

Coordinates of `1 kg,2kg,3kg` are `(0,)`
`(2,0),(1,sqrt(3))` respectively
`(x_(cm),y_(cm))=(0,0)`
