Given: Fт1 (gravity acting on the Earth) = 29.4 N.
Constants: by condition we take gz (acceleration of gravity on Earth) = 9.8 N / kg; gl (acceleration of gravity on the Moon) = 1.6 N / kg.
Since the mass of the body remains constant, the force of gravity that will act on the body on the surface of the Moon is determined from the equality: m = Ft1 / gz = Ft2 / gl, whence Ft2 = Ft1 * gl / gz.
Calculation: Ft2 = 29.4 * 1.6 / 9.8 = 4.8 N.
Answer: The force of gravity acting on a body on the Moon is 4.8 N.
