These tasks: m (the mass of the body in question) = 400 g (in SI m = 0.4 kg); for the calculation, we assume that the body is on the surface of the Earth (h = 0 m).

Reference values: g (acceleration due to gravity) = 9.8 m / s2.

The force of attraction of the body under consideration to the Earth can be determined by the formula: F = G * m * Mz / (Rz + h) = G * m * Mz / Rz = m * g.

Let’s make a calculation: F = 0.4 * 9.8 = 3.92 N.

Answer: The body in question is attracted to the Earth with a force of 3.92 N.
