A boy weighing 500 N holds a body weighing 50 N with what force does he press on the ground?

From the law of universal gravitation, discovered by Newton, it follows that F = m * g, where F is the force (of gravity), m is the mass of the body, and g is the acceleration of gravity.

In this problem, the total mass will be equal to the sum of the masses of the boy and the other body. That is, m = m1 + m2 = 500 N + 50 N = 550 N.

F = mg = 550 N * 9.8 m / s ^ 2 = 5390 N = 5390/1000 kN = 5.39 kN.

Answer: F = 5.39 kN.
