Answer:
The force between them is, F = 8.33 x 10⁻¹¹ N
Explanation:
Given data,
The distance between the proton and electron, x = 12 nm
= 12 x 10⁻⁹ m
The electrostatic force between them is given by the formula,
[tex]F=k\frac{q_{1}q_{2} }{x^{2} }[/tex]
Where k = 9 x 10⁹ Nm²C⁻²
Substituting the given values,
[tex]F=9\times10^{9} \frac{1\times 1 }{(12 \times 10^{9}) ^{2} }[/tex]
F = 8.33 x 10⁻¹¹ N
Hence, the force between them is, F = 8.33 x 10⁻¹¹ N
