Two particles of masses 1 kg and 2 kg are located at

{x_1} = 0,\;{y_1} = 0\,and\,{x_2} = 1,\;{y_2} = 0

respectively. The centre of mass of the system is at

View answer and explanation

Correct option: D

x = \frac{2}{3},\;y = 0

Option D (

x = \frac{2}{3},\;y = 0

) is correct because the center of mass coordinates are calculated using the formulas

x_{cm} = (m_1x_1 + m_2x_2) / (m_1 + m_2)

and

y_{cm} = (m_1y_1 + m_2y_2) / (m_1 + m_2)

.
