Question

Обозначить силу взаимодействия двух электронов , размещенных на расстоянии 1 мкм

Answer 1

$F= \frac{k*|q1|*|q2|}{r^2}$; q1=q2=-1.6*10^-19 Кл; k=9*10^9 Н*м^2/Кл^2;
F=(9*10^9*1.6*10^-19*1.6*10^-19)/(1*10^-6)^2=2.3*10^-16 Н
Ответ: F=2.3*10^-16 Н

Answer 2

Force of Interaction Between Two Electrons

The force of interaction between two electrons placed at a distance of 1 µm can be calculated using Coulomb's law, which states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

The formula for the force of interaction (F) between two point charges q1 and q2 separated by a distance r is given by:

F = k * (|q1 * q2|) / r^2 Where: - F is the force of interaction - k is the Coulomb's constant (approximately 8.9875 x 10^9 N m^2 C^-2) - q1 and q2 are the magnitudes of the charges - r is the distance between the charges

In the case of two electrons, each with a charge of approximately -1.602 x 10^-19 C, the force of interaction can be calculated using the above formula with the given distance of 1 µm (1 µm = 1 x 10^-6 m).

Using the values: - q1 = -1.602 x 10^-19 C - q2 = -1.602 x 10^-19 C - r = 1 x 10^-6 m

We can calculate the force of interaction between the two electrons using the Coulomb's law formula.

Calculation

Using the formula: F = k * (|q1 * q2|) / r^2

Substituting the values: F = (8.9875 x 10^9 N m^2 C^-2) * (|-1.602 x 10^-19 C * -1.602 x 10^-19 C|) / (1 x 10^-6 m)^2

Calculating the above expression gives the force of interaction between the two electrons placed at a distance of 1 µm.

This calculation yields the force of interaction between the two electrons at the given distance.
