Three particles each 1kg mass are placed...

Three particles each `1kg` mass are placed at the corners of a right angled triangle `AOB`, `O` being the origin of the co-ordinate system `OA` and `OB` along `+ve` x-direction and `+ve` y-direction. The position vector of the centre of mass is (`OA = OB=1m`) (in meters)

A

`(i+j)/3`

B

`(i-j)/3`

C

`(2(i+j))/3`

D

`(i-j)`

Text Solution
