When hanging the load on the hook of the dynamometer, it was found that the force of attraction of the load to the Earth is 1.96 N. What is the mass of the load?
Ft = 1.96 N.
g = 9.8 m / s ^ 2.
The force of attraction of bodies on the surface of the earth is called the force of gravity Ft and is determined by the formula: Ft = m * g, where m is the mass of the body, g is the acceleration of gravity on the surface of the earth.
m = Fт / g.
m = 1.96 N / 9.8 m / s ^ 2 = 0.2 kg.
Answer: the mass of the cargo is m = 0.2 kg.
