Electro Statics...What am I missing!?
A balloon rubbed against denim gains a charge of 8.0microcoulumbs (I can't do the sign ). What is the electric force between the denim and balloon when the two are separated by a distance of 5.0 cm?
Coulumb's law: Fe = Kc q1q2/r^2
Ok, so I was given q1: 8mc I know Kc: 8.99*10^9 and I know R: 5 cm This leaves q2, how am I to know what the charge of q2 is? Could it be the standard 1.60219 * 10^-19? Or is the charge transferred?
