Question

Два одинаковых маленьких проходящих шарика имеющие электрические заряды 1.8*10^-8кл и -2*10^9 соприкоснулись с какой силой они будут взаимодействовать если их разместить на расстоянии 8мм друг от друга. Помоги пожалуйста

Answer 1

По закону Кулона
F=kq1q2/r²
F=9×10^9×1.8×10^-8×(-2×10^-9/8×10³
F=-4,05×10^-5 Н

Answer 2

Calculating the Force of Interaction Between Two Charged Spheres

To calculate the force of interaction between two charged spheres, we can use Coulomb's law, which states that the force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between their centers.

The formula for Coulomb's law is:

F = k * |q1 * q2| / r^2

Where: - F is the force between the charges - k is 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 centers of the charges

Calculating the Force of Interaction

Given: - Magnitude of charge 1 (q1) = 1.8 x 10^-8 C - Magnitude of charge 2 (q2) = -2 x 10^-9 C (negative sign indicates the charge is negative) - Distance between the charges (r) = 8 mm = 8 x 10^-3 m

Using Coulomb's law, we can calculate the force of interaction between the two charges:

F = (8.9875 x 10^9 N m^2/C^2) * |(1.8 x 10^-8 C) * (-2 x 10^-9 C)| / (8 x 10^-3 m)^2

Now, let's calculate the force using the given values.
