Question

Два шарика, расположенные на расстоянии 10 см друг от друга , имеют одинаковые отрицательные заряды и взаимодействует с силой 0,23мН. Найти заряд каждого шарика!!!

Answer 1

F= rq1q2/ r^2= kq^2 / r^2
Найдем заряд шарика  q= r * из дроби F/k = 0,1 * корень из  0,00023/ 9*10^9=1,59* 10^-8 Кл 
 число электронов можно найти разделив этот заряд на заряд одного электрона
N= q / qe= 1,59*10-8  /  1,6*10^-19=0,99 * 10^11

Answer 2

Finding the Charge of Each Ball

To find the charge of each ball, we can use the formula for the electric force between two charged objects:

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

Where: - F is the force between the two objects, - k is the electrostatic constant (approximately 9 * 10^9 Nm^2/C^2), - q1 and q2 are the charges of the two objects, and - r is the distance between the centers of the two objects.

In this case, we have two balls with the same negative charge and a force of 0.23 mN acting between them. The distance between the balls is 10 cm.

Let's calculate the charge of each ball using the given information.

Using the formula for electric force, we can rearrange it to solve for the charge of one of the balls:

q = (F * r^2) / (k * |q2|)

Substituting the given values: - F = 0.23 mN = 0.23 * 10^-3 N - r = 10 cm = 10 * 10^-2 m - k = 9 * 10^9 Nm^2/C^2

We need to find the value of |q2|, the charge of the other ball. Unfortunately, the exact value of |q2| is not provided in the question. However, we can still find the charge of each ball by considering different possible values for |q2|.

Let's consider two scenarios: one where |q2| is positive and one where |q2| is negative. We'll calculate the charge of each ball for both scenarios.

Scenario 1: |q2| is Positive
