At a height of

10 \mathrm{~km}

above the surface of earth, the value of acceleration due to gravity is the same as that of a particular depth below the surface of earth. Assuming uniform mass density of the earth, the depth is

View answer and explanation

Correct option: D

20 \mathrm{~km}

Option D (

20 \mathrm{~km}

) is correct because the depth at which the acceleration due to gravity is the same as at a height of 10 km is twice the height, assuming uniform mass density.
