From the formula of the law of universal gravitation, discovered by Newton, F = mg we express the mass (m).
m = F / g.
The value of g (acceleration of gravity) in the solution will be taken as 9.8 m / s ^ 2 – a constant, an approximate value.
So, m = F / g = 10 kN / 9.8 m / s ^ 2 = 10000 N / 9.8 m / s ^ 2 ≈ 1020 m.
Answer: m = 1020 m.
