Find the force with which two bodies weighing 20 kg and 40 kg are attracted at a distance of 10 m.

Task data: m1 (mass of the first body) = 20 kg; m2 (mass of the second body) = 40 kg; r (distance between given bodies) = 10 m.

Reference values: G (gravitational constant) = 6.674 * 10-11 m3 / (s2 * kg).

To determine the force of attraction between the given bodies, we will use the formula: F = G * m1 * m2 / r ^ 2.

Calculation: F = 6.674 * 10 ^ -11 * 20 * 40/10 ^ 2 = 53.392 * 10 ^ -11 N ≈ 534 * 10 ^ -12 N (534 pN).

Answer: Two given bodies must be attracted with a force of 534 pN.
