Two objects of mass 10 kg and 20 kg respectively are connected to the two ends of a rigid rod of length 10 m with negligible mass. The distance of the center of mass of the system from the 10 kg mass is :
Answer & explanation
Correct answer: option 2
Xcm = \(\frac{m_1 x_1 + m_2 x_2}{m_1 + m_2}\)
m1 = 10 Kg ; m2 = 20 Kg ; x1 = 0 m ; x2 = 10 m
Xcm = \(\frac{20}{3}\) m
