1. The problem statement, all variables and given/known data We're given pressure (Which is mass/volume) and G constant Looking for minimum r, given pressure, that would produce a certain F value in Newtons... 2. Relevant equations F=ma Blanking here* Honestly everyone this is my first physics intense college course and i have no idea where to begin. Yes, we are given reading materials. Nothing I can directly apply with the units... Maybe I need to look again? 3. The attempt at a solution my attempt is setting up variables and googling. I d o not know what I'm doing . Bless you physics forum devoteess.
