Left over from the big-bang beginning of the universe, tiny black holes might still wander through the universe. if one with a mass of 3 × 10^11 kg (and a radius of only 1 × 10^-16 m) reached earth, at what distance from your head would its gravitational pull on you match that of earth's? assume free-fall acceleration ag=9.83 m/s2.

Explanation:

It is given that,

Mass,

Acceleration due to gravity,

Acceleration due to gravity is given by :

r = distance from head

r = 1.42 m

So, at the distance of 1.42 meters from the head its gravitational pull on you match that of Earth's. Hence, this is the required solution.
