Ответ:

Сила электрического взаимодействия между двумя ядрами гелия равна 23,04 · 10⁻²⁹ H

Примечание:

Так как сила гравитационного взаимодействия на очень много порядков меньше силы электрического взаимодействия, то ей можно пренебречь.

Ядро гелия состоит из 2 протонов

Объяснение:

Дано:

r = 1 м

q_{1} = q_{2} = e = 1,6 · 10⁻¹⁹ Кл

k = 9 · 10⁹ (H · м²) / (Кл²)

Найти:

F \ - \ ?

------------------------------------------------

Решение:

Закона Кулона:

\boldsymbol{\boxed{F = \frac{k|q_{1}||q_{2}|}{r^{2}}}}

Расчеты:

F = (9 · 10⁹ (H · м²) / (Кл²) · 2,56 · 10⁻³⁸ Кл²) / (1 м²) = 23,04 · 10⁻²⁹ H

Ответ: F = 23,04 · 10⁻²⁹ H.
