Answer:
The electric force between them is 878.9 N
Explanation:
Given:
Identical charge [tex]q = -6.25 \times 10^{-6}[/tex]C
Separation between two charges [tex]r = 0.02[/tex] m
For finding the electrical force,
According to the coulomb's law
[tex]F = \frac{k q^{2} }{r^{2} }[/tex]
Here, force between two balloons are repulsive because both charges are same.
Where [tex]k = 9 \times 10^{9}[/tex]
[tex]F = \frac{9 \times 10^{9} \times (-6.25 \times 10^{-6} )^{2} }{4 \times 10^{-4} }[/tex]
[tex]F = 878.9[/tex] N
Therefore, the electric force between them is 878.9 N
