alleryTwo masses 2 kg and 6 kg are at x=0 m and x=4 m. Where is their centre of mass?
A3 m from the 2 kg mass
B4 m from the 2 kg mass
C2 m from the 2 kg mass
D1 m from the 2 kg mass
Answer & Solution
Correct answer: A. 3 m from the 2 kg mass
The weighted position is (2×0 + 6×4) divided by 8, or 3 m.
