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.
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.
