NEET 2022 Physics Center of Mass MCQ Question

Type: MCQ-numerical-Medium-Class 11

Two objects of mass 10 kg and 20 kg respectively are connected to the two ends of a rigid rod of length 10 m with negligible mass. The distance of the center of mass of the system from the 10 kg mass is:

A

10 m

B

5 m

C

10/3 m

D

20/3 m

Correct Answer

Option C

Detailed Explanation

The center of mass is calculated using the formula: (m1x¹⁺ m²x2) / (m¹⁺ m²). Here, m1 = 10 kg, m² = 20 kg, x1 = 0, x2 = 10 m. The center of mass is 20/3 m from the 10 kg mass.
