NEET Physics Centre of Mass MCQ Question
A system consists of two particles of masses m1 = 2 kg and m2 = 3 kg, located at positions x1 = 1 m and x2 = 4 m along the x-axis. What is the x-coordinate of the center of mass of the system?
8 m
0 m
0 m
5 m
Correct Answer
Detailed Explanation
The x-coordinate of the center of mass is given by (m1 * x1 + m2 * x2) / (m1 + m2). Substituting the values, we get (2 * 1 + 3 * 4) / (2 + 3) = 14 / 5 = 2.8 m.
