![### Electrostatic Experiment: Charged Balloon and Rod
**Problem Statement:**
A 2.00 g air-inflated balloon is given an excess negative charge, \( q_1 = -3.00 \times 10^{-8} \) C, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of \( d = 6.80 \) cm to make the balloon float. Assume the balloon and rod to be point charges. The Coulomb force constant is \( \frac{1}{4\pi \epsilon_0} = 8.99 \times 10^9 \) N·m²/C² and the acceleration due to gravity is \( g = 9.81 \) m/s².
**Question 1:**
In order for this to occur, what polarity of charge must the rod possess?
- \( q_2 \) is positive
- \( q_2 \) is negative
- \( q_2 \) is a proton
- \( q_2 \) is neutral
**Question 2:**
How much charge \( q_2 \) does the rod have?
\[ q_2 = \quad \boxed{\phantom{}} \text{ C} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F37e1db01-06d0-4e20-aae1-26f96b6814c3%2F4af23ebc-c605-4469-a83c-143867dfa920%2Fj21jpi_processed.png&w=3840&q=75)
