Given :
- q₁ = 3.37 μC
- q₂ = - 8.21 μC
- F = 0.0626 N
To find :
- Distance between the balloons
Solution :
- Let the distance between the two balloons be d.
- We know that, force between two charges is given by coulomb's law.
- Hence, by Coulomb's law,
F = (1/4πε₀) [(q₁ q₂) / d²]
∴ 0.0626 = (9 × 10⁹) ( 3.37 × 10⁻⁶ × 8.21 × 10⁻⁶ ) ÷ d²
∴ d² = 3.977 ≈ 4
∴ d = 2 m
Answer : The separation distance between the two balloons is 2 m.
