Answer:0.506 N
Explanation:
Given
Charge on first balloon [tex]q_1=6\ \mu C[/tex]
Charge on second balloon is [tex]q_2=6\ \mu C[/tex]
Distance between them [tex]r=0.8\ m[/tex]
Electrostatic Repulsive force is given by
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
Where K is constant
[tex]F=\dfrac{9\times 10^9\times 6\times 10^{-6}\times 6\times 10^{-6}}{(0.8)^2}[/tex]
[tex]F=\dfrac{324\times 10^{-3}}{0.64}[/tex]
[tex]F=0.506\ N[/tex]
