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 2.0cm above 1.5 kg mass

D

0.9cm left and 2.0cm above 1.5 kg mass

Text Solution

Verified by Experts

The correct Answer is:
C
`X_(cm)=(1.5xx0.+1xx3+2.5xx0)/(5)`
=0.6 cm
`Y_(cm)=(1.0xx0+1.5xx0+2.5xx4)/(5)`
=2cm.
