Answer:
35870474.30504 m
Explanation:
r = Distance from the surface
T = Time period = 24 h
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
m = Mass of the Earth = 5.98 × 10²⁴ kg
Radius of Earth = ![6.38\times 10^6\ m](https://tex.z-dn.net/?f=6.38%5Ctimes%2010%5E6%5C%20m)
The gravitational force will balance the centripetal force
![\dfrac{GMm}{R^2}=m\dfrac{v^2}{R}\\\Rightarrow v=\sqrt{\dfrac{GM}{R}}](https://tex.z-dn.net/?f=%5Cdfrac%7BGMm%7D%7BR%5E2%7D%3Dm%5Cdfrac%7Bv%5E2%7D%7BR%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B%5Cdfrac%7BGM%7D%7BR%7D%7D)
![T=\dfrac{2\pi r}{v}\\\Rightarrow T=\dfrac{2\pi r}{\sqrt{\dfrac{GM}{r}}}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B2%5Cpi%20r%7D%7Bv%7D%5C%5C%5CRightarrow%20T%3D%5Cdfrac%7B2%5Cpi%20r%7D%7B%5Csqrt%7B%5Cdfrac%7BGM%7D%7Br%7D%7D%7D)
From Kepler's law we have relation
![T^2=\dfrac{4\pi^2r^3}{GM}\\\Rightarrow r^3=\dfrac{T^2GM}{4\pi^2}\\\Rightarrow r=\left(\dfrac{(24\times 3600)^2\times 6.67\times 10^{-11}\times 5.98\times 10^{24}}{4\pi^2}\right)^{\dfrac{1}{3}}\\\Rightarrow r=42250474.30504\ m](https://tex.z-dn.net/?f=T%5E2%3D%5Cdfrac%7B4%5Cpi%5E2r%5E3%7D%7BGM%7D%5C%5C%5CRightarrow%20r%5E3%3D%5Cdfrac%7BT%5E2GM%7D%7B4%5Cpi%5E2%7D%5C%5C%5CRightarrow%20r%3D%5Cleft%28%5Cdfrac%7B%2824%5Ctimes%203600%29%5E2%5Ctimes%206.67%5Ctimes%2010%5E%7B-11%7D%5Ctimes%205.98%5Ctimes%2010%5E%7B24%7D%7D%7B4%5Cpi%5E2%7D%5Cright%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5CRightarrow%20r%3D42250474.30504%5C%20m)
Distance from the center of the Earth would be
![42250474.30504-6.38\times 10^6=\mathbf{35870474.30504\ m}](https://tex.z-dn.net/?f=42250474.30504-6.38%5Ctimes%2010%5E6%3D%5Cmathbf%7B35870474.30504%5C%20m%7D)
