Determine the force of gravity acting on a body weighing 3.5 kg; 400 g; 1.5 t; 60 g

We solve the problem according to Newton’s second law F = mg (where m is the mass of the body, g is the acceleration of gravity = 9.8 m / s2)
when solving the problem, the mass in the condition must be converted into kg 400 g = 0.4 kg, 1.5 tons = 1500 kg, 60 g = 0.06 kg.
the acceleration of gravity is taken equal to 10 m / s2
Accordingly for each weight:
F1 = 3.5×10 = 35H
F2 = 0.4×10 = 4H
F3 = 1500×10 = 15000 N
F4 = 0.06×10 = 0.6 N
