Three particles of masses 1kg,2kg and 3kg are placed at the vertices A,B and C of an equilateral triangle ABC. If A and B lie at (0,0) and (1,0)m, the co-ordinates of their centre of mass are

Three particles of masses 1kg,2kg and 3kg are placed at the vertices A

1.	Three particles of masses 1kg,2kg and 3kg are placed at the vertices A,B and C of an equilateral triangle ABC. If A and B lie at (0,0) and (1,0)m, the co-ordinates of their centre of mass are
Answer» `((SQRT(3))/(2)m"and"(7)/(6)m)` `((7)/(6)m"and"(sqrt(3))/(4)m)` `((7)/(12)m"and"(sqrt(3))/(4)m)` `((7)/(12)m"and"(7)/(12)m)` ANSWER :C
