Is anybody aware of an equation that can be used to describe a floating ball in an air jet?(adsbygoogle = window.adsbygoogle || []).push({});

I'd just like to put numbers into an equation and prove that the forces on either side of the ball are equal.

the balls mass is 2g

take gravity as 9.81ms ?

F=ma (0.002kg x 9.81) = 0.0196N

that should be the component of force acting downwards upon the ball, would you agree?

Now i'd like to find a way of calculating the force acting up on the ball, which I'd expect to be close to the figure above. Any suggestions ?

I dunno if i'm on the right track because i'm a bit thick but should I be looking into the drag coefficient equation ?
