The force of attraction between the balloon and the rod is 9 x 10⁻³ N.
Force of attraction between the balloon and the rod
The force of attraction between the balloon and the rod is calculated by applying Coulomb's law as shown below;
[tex]F = \frac{kq_1 q_2}{r^2}[/tex]
where;
- r is the distance between the charges
- k is Coulomb's constant = 9 x 10⁹ Nm²/C²
F = (9 x 10⁹) x (2.0 x 10⁻⁸)²/(0.02)²
F = 9 x 10⁻³ N
Thus, the force of attraction between the balloon and the rod is 9 x 10⁻³ N.
