The answer is D. mass ...
Explanation:
It is given that,
Density of asteroid, 
Mass of asteroid, 
We need to find the diameter of the asteroid. The formula of density is given by:

V is the volume of spherical shaped asteroid, 



r = 2441311.12 m
Diameter = 2 × radius
d = 4882622.24 m
or

Hence, this is the required solution.
By the newtons Second Law:
F = ma
Solving for m:
m = F / a
m = 100 N / 2 m/s²
<h3>m = 50 kg → ANSWER</h3>
