Consider four point masses: the 1.0 kg mass is 1.0 m from the origin, the 2.0 kg mass is 2.0 m from the origin, the 3.0 kg mass is 3.0 m from the origin, and the 4.0 kg mass is located 4.0 m from the origin. The acceleration due to gravity is the same everywhere. What is the x coordinate of the center of gravity for this system?
A) 2.0 m
B) 2.7 m
C) 3.0 m
D) 3.3 m
E) 3.8 m
