Analyzing +4 | -1

Statement-1: If the centre of mass of a system is the origin then the total mass to the right of origin is same as total mass to left of origin.
Statement-2:

x_{\mathrm{cm}}=\frac{\Sigma_{m_i x_i}}{\Sigma_{m_i}}

View answer and explanation

Correct option: D

Statement-1 is false, Statement-2 is true

Option D is correct because Statement-1 is false (it's about the sum of m_i*x_i, not total mass), and Statement-2 is true (it's the correct formula for the center of mass).
