Question

Two masses 10kg and 20kg are separated by distance r, find the position of centre​

Answer 1

Answer:

Center of mass of system of two given masses is at distance 2r/3 from 10 kg mass

Explanation:

Two masses 10 kg and 20 kg are separated by distance "r"

So here the position of center of mass with respect to 10 kg we will take our reference at position of 10 kg mass

so we have

$r_{cm} = \frac{m_1r_1 + m_2r_2}{m_1 + m_2}$

so we will have

$r_{cm} = \frac{10 (0) + 20 (r)}{10 + 20}$

$r_{cm} = \frac{20 r}{30}$

$r_{cm} = \frac{2r}{3}$
