NEET Physics Centre of Mass MCQ Question
Two point masses, m1 = 2 kg and m2 = 3 kg, are placed on a frictionless surface at positions (2, 0) m and (5, 0) m, respectively. What is the x-coordinate of the center of mass of this system?
8 m
0 m
0 m
2 m
Correct Answer
Detailed Explanation
The x-coordinate of the center of mass is calculated using the formula: (m1x1 + m2x2) / (m1 + m2). Substituting the given values: (22 + 35) / (2 + 3) = 3.8 m.
