Answer:
The distance between the charges is 9.5 cm
(c) is correct option
Explanation:
Given that,
Charge [tex]q= 10^{-6}\ C[/tex]
Force F = 1 N
We need to calculate the distance between the charges
Using Coulomb's formula
[tex]F = \dfrac{kq_{1}q_{2}}{r^2}[/tex]
Where, q = charge
r = distance
F = force
Put the value into the formula
[tex]1=\dfrac{9.0\times10^{9}\times(-10^{-6})^2}{r^2}[/tex]
[tex]r=\sqrt{9\times10^{9}\times(-10^{-6})^2}[/tex]
[tex]r=0.095\ m[/tex]
[tex]r= 9.5\ cm[/tex]
Hence, The distance between the charges is 9.5 cm
