Inverse Square Law: Saving Stacy Stacy has aspirations of being a famous TikTok-er /molecular biologist. Furthermore, as an astute practitioner of time management skills, Stacy has hundreds of videos stored on her phone for future TikToks. However, such a strategy does not come without risks. Being the careful professional that she is, Stacy is aware that if her phone experiences a Coulomb force greater than 40 N for a prolonged period of time, then all of her videos will be erased! One Spring day in her Physics 5C section, Stacy notices that Marvin, who sits 2 m away from her, is stowing (1000/9) nC of charge in his pocket. If Stacy's phone has a charge of 1 C, how far should Stacy ask Marvin to move away from her to preserve her TikToks?
