Problem

The gravitational field intensity due to a certain asteroid is measured to be

1.0\,\text{N\,kg}^{-1}

at a point on its axis. If the mass of the asteroid is

8.0 \times 10^{22}\,\text{kg}

, determine the distance of this point from the asteroid’s centre. Take

G = 6.67 \times 10^{-11}\,\text{N\,m}^2\text{kg}^{-2}
