Give the expression for the centre of mass of a system of particles along any one axis.

Text Solution

Verified by Experts


`X=(m_1x_1+m_2x_2)/(m_1+m_2)`
Note: For n particles (discrete)
`x=(overset(n)underset(i_1=1)summ_iR_i)/(overset(n)underset(i=1)(summ_i))` and `summ_i=M`=mass of the whole body.
