Question

Collate the electrical force between and electrons and protons in an atom that are separated by distance of 5.9 e -11m

Answer 1

Answer:

The electrical force between the electrons and protons in the atom is 6.62 x 10⁻⁸ N.

Explanation:

Given;

distance between the electron and proton, r = 5.9 x 10⁻¹¹ m

charge of electron, q₁ = -1.6 x 10⁻¹⁹ C

charge proton, q₂ = +1.6 x 10⁻¹⁹ C

The electric force between the two particles is calculated by Coulomb's law;

$F = \frac{k|q_1|q_2|}{r^2} \\\\F = \frac{(9\times 10^9) \times (1.6\times 10^{-19})^2}{(5.9\times 10^{-11})^2} \\\\F = 6.62 \times 10^{-8} \ N$

Therefore, the electrical force between the electrons and protons in the atom is 6.62 x 10⁻⁸ N.
