If the acceleration due to gravity experienced by a point mass at a height above the surface of earth is same as that of the acceleration due to gravity at a depth ) from the earth surface. The value of will be _____ .
(use )
Correct answer: 2
Solution
Acceleration due to gravity at a height above the earth's surface is given by
And acceleration due to gravity at depth below the earth surface is given by .
As
So,
Thus, the value of .
Hence, the correct answer is 2.
