The electric charges of the two clouds are 20 C and -30 C. Assuming that the average distance between clouds

The electric charges of the two clouds are 20 C and -30 C. Assuming that the average distance between clouds is 30 km, estimate the strength of the interaction between them.

Problem data: q1 (electric charge of the first cloud) = 20 C; q2 (charge of the second cloud) = -30 C; r (accepted average distance between these clouds) = 30 km (30 * 10 ^ 3 m).

Reference values: k (proportionality coefficient) = 9 * 10 ^ 9 N * m2 / Cl2.

The force of interaction between two given clouds can be calculated using the formula: F = k * | q1 | * | q2 | / r ^ 2.

Let’s calculate: F = 9 * 10 ^ 9 * | 20 | * | -30 | / (30 * 10 ^ 3) ^ 2 = 6,000 N (6 kN).

Answer: The clouds must interact with a force of 6 kN.
