Answer 2

Answer:

The center of mass of two particle system is g.

Explanation:

Given that,

Mass of small particle = 2 kg

Mass of large particle = 4 kg

Angle = 45°

Acceleration of both particles is same, which is equal to the acceleration due to gravity.

So, the acceleration of both particles are g.

We need to calculate the center of mass of two particle system

Using formula of center of mass

$a_{cm}=\dfrac{m_{1}a_{1}+m_{2}a_{2}}{m_{1}+m_{2}}$

Put the value into the formula

$a_{cm}=\dfrac{2\times g+4\times g}{2+4}$

$a_{cm}=\dfrac{6g}{6}$

$a_{cm}=g$

Hence, The center of mass of two particle system is g.
