Answer:
[tex]20,000\:\mathrm{N}[/tex]
Explanation:
The weight of an object on Earth is equal to the force of gravity on that object.
We can use the following equation to determine the force of gravity on an object:
[tex]F_g=ma_g=mg[/tex], where [tex]m[/tex] is the mass of the object and [tex]g[/tex] is acceleration due to gravity ([tex]9.81\: \mathrm{m/s}[/tex]).
Solving, we get:[tex]F_g=2,000\cdot9.81=19,620=\fbox{$20,000\:\mathrm{N}$}[/tex] (one significant figure).
