Two objects of mass \( 10 \mathrm{~kg} \) and \( 20 \mathrm{~kg} \) respectively are connected to the two ends of a rigid rod of length \( 10 \mathrm{~m} \) with negligible mass. The distance of the centre of mass of the system from the \( 10 \mathrm{~kg} \) mass is :
(1) \( 5 m \)
(2) \( \frac{10}{3} \mathrm{~m} \)
(3) \( \frac{20}{3} m \)
(4) \( 10 \mathrm{~m} \)
