The electric charges of the two clouds are, respectively, 20 and 30C. the distance

The electric charges of the two clouds are, respectively, 20 and 30C. the distance between the points is 30 km. With what force they interact.

q1 = 20 Cl.

q2 = 30 Cl.

k = 9 * 10 ^ 9 N * m ^ 2 / Kl ^ 2.

r = 30 km = 30,000 m.

F -?

According to Coulomb’s law, the force of interaction F between two charges q1 and q2 is directly proportional to the values of these charges, and inversely proportional to the square of the distance r between them: F = k * q1 * q2 / r ^ 2, where k is the proportionality coefficient.

F = 9 * 10 ^ 9 N * m ^ 2 / Kl ^ 2 * 20 Kl * 30 Kl / (30,000 m) ^ 2 = 6000 N.

Answer: between the clouds there is an interaction force F = = 6000 N.
