1.When the masses are on positive x axis:
Xcm=m1 x1 + m2 x2÷m1+m2
2.When the origin coincides with any one of masses:
The position x will be 0.
Xcm=m1(0) + m2 x2÷m1+m2
So,
Xcm=m2 x2÷m1+m2
Xcm=m1 x1 + m2 x2÷m1+m2
2.When the origin coincides with any one of masses:
The position x will be 0.
Xcm=m1(0) + m2 x2÷m1+m2
So,
Xcm=m2 x2÷m1+m2
