physics

$\frac{2ma}{g + a}$

$\frac{2ma}{g - a}$

Explanation

To solve this problem, we need to analyze the forces acting on the balloon in both scenarios: when it is descending and when it is ascending. $\\$ 1. When the balloon is descending with acceleration $a: \\$ • The gravitational force acting on the balloon is $mg. \\$ • The net force acting on the balloon is $F_{net} = m(g - a). \\$
