Q. Two balls are thrown vertically upward simultaneously. While they are in air, the acceleration of their centre of mass

Depends on the masses of the balls

Depends on volume of the balls

Depends on the speed of the balls

Is equal to acceleration due to gravity

$a_{c m} = \frac{- m g j ^ - m g j ^}{2 m}$
$∣ ∣ a_{c m} ∣ ∣ = g$

Is equal to acceleration due to gravity

acm​​=2m−mgj^​−mgj^​​ ∣∣​acm​​∣∣​=g

$a_{c m} = \frac{- m g j ^ - m g j ^}{2 m}$
$∣ ∣ a_{c m} ∣ ∣ = g$
