The gravitational force has a universal range and is felt by all objects that have a mass and is always an attractive force and never repulsive.

d = 0.479 m

Explanation:

Given that,

The distance light travels in = 1.6 ns

The speed of light is $2.998\times 10^8\ m/s$

The speed of an object is given by distance traveled divided by time.

$c=\dfrac{d}{t}\\\\d=ct\\\\d=2.998\times 10^8\times 1.6\times 10^{-9}\\\\=0.479\ m$

Hence, the required distance is 0.479 m.
