The expression for the acceleration of gravity is $)2$ where:

GRAVITATIONAL$\_$CONSTANT $=$ the gravitational constant $(6\mathrm{.}673e-11).$

MASS$\_$OF$\_$EARTH $=$ the mass of the Earth in $kg(5\mathrm{.}98e+24).$

distance$\_$center $=$ the distance in meters from the Earth's center, read from input into variable distance$\_$center.

Compute the approximate acceleration of gravity for an object above the Earth's surface. Assign gravity$\_$acceleration with the result.

Note:

The input value is a floating$-$point literal written in scientific notation using an $"$e$"$ preceding the power$-$of$-10$ exponent. The $"$e$"$ stands for exponent.

Ex: $6\mathrm{.}02e23$ represents $6\mathrm{.}02{10}^{23},$ while $1\mathrm{.}0e-3$ represents $1{10}^{-3}$ or $0\mathrm{.}001.$
