Two particles of mass 5 kg and 10 kg respectively are attached to the twoends of a rigid rod of length 1 m with negligible mass. the centre of mass of the system from the 5 kg particle is nearly at a distance of :

Options

A. 50 cm
B. 67 cm
C. 80 cm
D. 33 cm

Explanation

For two bodies system
`x _(cm) = ( m _(1) x _(2) + m _(2) x _(2))/( m _(1) + m _(2))`
`= ( 5 xx 0 + 100 xx 10)/( 5 + 10) = (200)/(3) = 66.66 cm`
