Answer:
3600km
Explanation:
gravitational constant is the gravitational attraction between any two things
G = gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg²
g = acceleration due to gravity = 4 m/s²
M = mass of the earth = 6 × 10²⁴
r = radius of Earth + height of meteor
Since F = mg and F = GMm/r², mg = GMm/r²
g = GM/r²
r² = GM/g
r = √(GM/g)
r = √((6.67 × 10⁻¹¹ Nm²/kg²) × (6 × 10²⁴ kg))/(4 m/s²)) =
1 × 10⁷ m = 1 × 10⁴ km
To calculate the height of the meteor above the earth,
subtract the radius of the earth from the calculated radius.
height of meteor = 1 × 10⁴ km - 6 × 10³ km = 4 × 10³ km
