Question

Два неподвижных электрических заряда 10(-7) Кл и 3,4•10(-6) Кл взаимодействуют в керосине с силой 10 Н. Найти расстояние между ними.

Answer 1

Q₁=10⁻⁷ Кл                     выразим (r²) из з-на Кулона:
q₂=3,4 10⁻⁶ Кл                   F=k q₁q₂/r²  ⇒  r²=k q₁q₂/F;
k=9 10⁹ Н м²/Кл²               r²=9 10⁹*10⁻⁷*3,4 10⁻⁶/2,1*10= 14,57 10⁻⁴ м²;
ε=2,1                                 извлекаем это число из под корня квадратного:
F=10 H                              r =3,82 10⁻² м.
r-?                      Ответ:    r=3,82 10⁻² м.

Answer 2

Calculation of the Distance Between Two Fixed Electric Charges

To find the distance between two fixed electric charges, we can use Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Given: - Charge 1: q1 = 10^(-7) C - Charge 2: q2 = 3.4 * 10^(-6) C - Force: F = 10 N

We need to find the distance (r) between the charges.

Using Coulomb's law, we have the equation:

F = (k * q1 * q2) / r^2

Where: - F is the force between the charges - k is the electrostatic constant (k = 9 * 10^9 Nm^2/C^2) - q1 and q2 are the charges - r is the distance between the charges

Rearranging the equation to solve for r, we get:

r = sqrt((k * q1 * q2) / F)

Let's substitute the given values into the equation and calculate the distance.

r = sqrt((9 * 10^9 Nm^2/C^2 * 10^(-7) C * 3.4 * 10^(-6) C) / 10 N)

Calculating this expression gives us the distance between the charges.

Please note that the search results did not provide a specific value for the electrostatic constant (k), so we will use the commonly accepted value of 9 * 10^9 Nm^2/C^2.

Let's calculate the distance.
