Question

The value of acceleration due to
gravity on the surface of earth is
X. At an altitude of 'h' from the
surface of the earth, its value is y.
If R is the radius of earth, then
the value of his
-IR
​

Answer 1

Value of acceleration due to gravity at height h is g×(1+

R

h

)

2

where g is acceleration due to gravity on surface and h is measured from ground

so, y=x(1+

R

h

)

2

so, h=(

x

y

−1)R
