5. the radius of the earth is approximately 6,000 kilometers. the acceleration of an astronaut in a perfectly circular orbit 300 kilometers above the earth would be most nearly?

a = 10 m/s²

Explanation:

given,

Radius of earth = 6,000 Km

distance from earth = 300 Km

distance from the earth =

        = 6000 x 10³ + 300 x 10³

        = 6300 x 10³ m

       = 6.3 x 10⁶ m

we know,

F = m a

gravitational force

G is gravitational constant = 6.67 x 10⁻¹¹ m³/kg.s²

M is mass of earth = 5.972 x 10²⁴ Kg

a = 10 m/s²

acceleration of an astronaut is equal to 10 m/s²

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
