What will be the weight of an astronaut on the Moon if, under terrestrial conditions, his weight is 700 N? Acceleration of gravity on Earth is considered equal to 10 m / s ^ 2, on the Moon -1.7 m / s ^ 2.

Pz = 700 N.
gz = 10 m / s ^ 2.
gl = 1.7 m / s ^ 2.
Rl -?
The weight of the body P is the force with which the body presses on the support or stretches the suspension.
The weight of an astronaut on the surface of the earth is determined by the formula: Pz = m * gz, where m is the mass of a person, gz is the acceleration of gravity on the surface of the Earth.
The weight of an astronaut on the lunar surface is determined by the formula: Pl = m * gl, where m is the mass of a person, gl is the acceleration of gravity on the lunar surface.
m = Pz / gz.
Pl = gl * Pz / gz.
Pl = 1.7 m / s ^ 2 * 700 N / 10 m / s ^ 2 = 119 N.
Answer: the weight of the astronaut on the lunar surface will be Pl = 119 N.
