Three idential spheres, each of mass 1 kg are placed touching each other with their centres on a straight line. Their centres are marked P, Q and R respectively. The distance of centre of mass of the system from P is :
- \(\frac{\mathrm{PQ}+\mathrm{PR}+\mathrm{QR}}{3}\)
- \(\frac{\mathrm{PQ}+\mathrm{PR}}{3}\)
- \(\frac{\mathrm{PQ}+\mathrm{QR}}{3}\)
- none of these
Answer
(B) PQ + PR 3
