A 2.00 g air‑inflated balloon is given an excess negative charge, ?1=−3.50×10−8 C, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of ?=5.40 cm to make the balloon float. Assume the balloon and rod to be point charges. The Coulomb force constant is 1/(4??0)=8.99×109 N⋅m2/C2 and the acceleration due to gravity is ?=9.81 m/s2. How much charge ?2 does the rod have?
