The position vectors of two bodies of equal masses are $rightwards arrow for straight r subscript 1 of and space rightwards arrow for straight r subscript 2 of$ . What is the position vector of their centre of mass?

Solution

Given position vectors of two bodies are r₁ and r_2.
Therefore, the position vector of their centre of mass is given by,
r = $fraction numerator rightwards arrow for straight r subscript 1 of plus rightwards arrow for straight r subscript 2 of over denominator 2 end fraction$
