Question

Two masses 2 kg and 6 kg lie on the x-axis at distances of 3 m and 6 m, respectively, from the origin. The distances of the centre of mass of the system from the origin and from the 2 kg mass are in the ratio

• A. 3 : 7
• B. 1 : 4
• C. 2 : 1
• D. 7 : 3
• E. 3 : 1

Hint:

To simplify the ratio \(5.25 / 2.25\), think in terms of 0.75 units. \(5.25 = 7 \times 0.75\) and \(2.25 = 3 \times 0.75\). This gives the ratio \(7:3\) immediately.

Answer 1

The Correct Option is D
