Question

Помогите пож с задачей. Заранее огромное Спасибо! С какой силой притягиваются два шарика, находящиеся в керосине на расстоянии 5см друг от друга, если заряд одного шарика 15 мкКл, а другого 20 мкКл?

Answer 1

F=k*q1*q2/e*R^2=9*10^9*15*10^-6*20*10^-6/2,1*25*10^-4=51,4 H

Answer 2

Calculation of the force between two charged spheres

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

The formula for Coulomb's law is:

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

Where: - F is the force between the two spheres, - k is the electrostatic constant (approximately equal to 9 × 10^9 N m^2/C^2), - q1 and q2 are the charges of the two spheres, and - r is the distance between the centers of the spheres.

In this case, the charge of one sphere is 15 μC (microcoulombs) and the charge of the other sphere is 20 μC. The distance between the spheres is 5 cm (or 0.05 m).

Let's calculate the force using these values:

F = (9 × 10^9 N m^2/C^2) * ((15 × 10^-6 C) * (20 × 10^-6 C)) / (0.05 m)^2

Calculating this expression gives us the force between the two spheres.

Please note that the above calculation assumes that the spheres are point charges and that the kerosene does not significantly affect the electric field between the spheres.

Let me calculate the force for you.
