Five masses are placed in a plane as shown in figure. The coordinates of the centre of mass are nearest to

A

1.2, 1.4

B

1.3, 1.1

C

1.1, 1.3

D

1.0, 1.0

Text Solution

Verified by Experts

The correct Answer is:
C
`X_(C.M)= ( 1 xx 0 + 2 xx 2 + 3 xx 0+4xx2+5xx1)/(1+2+3+4+5)`
`=(4+8+5)/(15)=(17)/(15) = 1.1`
`Y_(c.M) = (1xx 0+2 xx 0+ 3 xx 2 + 4 xx 2+5 xx1)/(1+2+3+4+5)`
` = (6+8+5)/(15) = 1.3`
