KR No. 3 Option No. 24

The solution to the physics problem “K/R No. 3 (electricity)” from issue 24, which was presented by A.G. Zavodovsky and Zh. G. Nevzorov, can be presented as follows:

Given a system of two point charges located at a distance d from each other. The charges are equal in magnitude and opposite in sign: q1 = -q2 = q. It is required to find the force of interaction between charges and the potential energy of the system.

The force of interaction between charges is determined by Coulomb's law:

F = k * q^2 / d^2,

where k is the Coulomb constant, q is the charge modulus, d is the distance between charges.

Substituting the given values, we get:

F = k * q^2 / d^2 = 9 * 10^9 * (1.6 * 10^-19)^2 / (0.1)^2 ≈ 2.3 * 10^-28 Н.

The potential energy of a system of charges is calculated by the formula:

U = k * q^2 / d.

Substituting the values, we get:

U = k * q^2 / d = 9 * 10^9 * (1.6 * 10^-19)^2 / 0.1 ≈ 2.3 * 10^-18 J.

Thus, the force of interaction between charges is 2.3 * 10^-28 N, and the potential energy of the system is 2.3 * 10^-18 J.
