Three masses are placed on the x-axis 300 g at origin, 500 g at x=40 cm and 400 g at x = 70 cm. The distance of the centre of mass from the origin is

View answer and explanation

Correct option: A

40 cm

Option A (40 cm) is correct because the distance of the center of mass from the origin is calculated using the formula

x_{CM} = \frac{\sum m_i x_i}{\sum m_i}

.
