Answer to Question #107592 in Mechanics | Relativity for Leandre Robinson

Question

A balloon remains stationary about 100 m above the ground. State what forces are acting on the balloon and explain how they result in no motion

Answer 1

The force of gravity acts on the balloon $-F_G$

and the power of Archimedes$-F_A$

So that the ball does not move, it is necessary that these forces are equal

$F_G=F_A$
