Three point particles of masses 1.0 kg, ...

Three point particles of masses 1.0 kg, 1.5 kg and 2.5 kg are placed at three corners of a right angle triangle as shown in figure. The centre of mass of the system is at a point :

A

1.5 cm left and 1.2 cm above 1.5 kg mass

B

2.2 cm left and 0.9 cm above 1.5 kg mass

C

0.6 cm left and 2.0 cm above 1.5 kg mass

D

0.9 cm left and 2.0 cm above 1.5 kg mass

Text Solution

Verified by Experts

The correct Answer is:
C
`X_(cm) = (1.5 xx 0 + 1 xx 3 + 2.5 xx 0)/(5)`
`= 0.6 cm`
`Y_(cm ) = (1.0 xx 0 + 1.5 xx 0 + 2.5 xx 4)/(5)`
`= 2 cm`
