A 0.00230 kg air-inflated balloon is given an excess negative charge q1 = -3.50 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 = 0.0560 m to make the balloon float. In order for this to occur, what polarity of charge must the rod possess? negative positive neutral O proton How much charge q2 does the rod have? Model the balloon and rod as point charges. The Coulomb force constant is 1/(4x) = 8.99 x 10° N-m²/C², and the acceleration due to gravity is g = 9.81 m/s² 92== 4,2834 x10-7 Incorrect
