A 0.00260 kg air-inflated balloon is given an excess negative charge q1 = -3.25 x 10-8 C by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of d = 0.0660 m to make the balloon float. In order for this to occur, what polarity of charge must the rod possess? positive neutral proton negative How much charge q2 does the rod have? Model the balloon and rod as point charges. The Coulomb force constant is 1/(4xe0) = 8.99 × 10° N-m2/C², and the acceleration due to gravity is g 9.81 m/s².
