With what force two books weighing 300g are attracted to each other. each located at a distance of 2m from each other?

Initial data: m (weight of each book) = 300 g, R (distance at which the books are from each other) = 2 m.

Reference values: G (gravitational constant) = 6.67 * 10 ^ -11 m3 / (s2 * kg).

SI system: m = 300 g = 0.3 kg.

The force with which the two books under consideration should be attracted can be calculated by the formula: F = G * m ^ 2 / R ^ 2.

Let’s perform the calculation: F = 6.67 * 10 ^ -11 * 0.3 ^ 2/2 ^ 2 = 0.15 * 10 ^ -11 H = 15 nN.

Answer: The books in question are attracted with a force of 15 nN.
