Q.
Two particles of mass 5 kg and 10 kg respectively are attached to the two ends of a rigid rod of length 1 m with negligible mass.
The centre of mass of the system from the 5 kg particle is nearly at a distance of :
A) 50 cm
B) 67 cm
C) 80 cm
D) 33 cm
Explanation
[Solution] $x = \frac{10 \times 1}{15} = 0.67$ m = 67 cm from the 5 kg mass. Answer (2).
