# Consider a two particle system with particles having masses m1 and m2. If the first particle is pushed towards the centre of mass through a distance d, by what distance should the second particle be moved, so as to keep the centre of mass at the same position? ?

Hello student,

Given,

the 2 masses are m1and m2

let x and y be the distance of m1and m2from the centre of mass respectively...

now, m1x = m2y

the mass m1 is moved by a distance d,

let the mass m2 be moved by a distance D

therefore, m1( x - d) = m2 (y -D )

= m1x - m1d = m2y - m2D

by eqn (i) m1x = m2y

= -m1d = -m2D

= D = (m1/m2) d

Thanks and Regards

Dear Student,

by eqn (i) m1x = m2y
= -m1d = -m2D
= D = (m1/m2) d
