Explanation:
The escape speed of an object from the surface of a planet/asteroid is given by:
where
G is the gravitational constant
M is the mass of the planet/asteroid
R is the radius of the planet/asteroid
In this problem we have
is the density of the asteroid
is the volume
So the mass of the asteroid is
The asteroid is approximately spherical, so its volume can be written as
where R is the radius. Solving for R,
Substituting M and R inside the formula of the escape speed, we find:
