$2\mathrm{.}12\mathrm{.}1$: Acceleration of gravity.

Compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: $\frac{G**M}{d^2},$ where $G$ is the gravitational constant $6\mathrm{.}673{10}^{-11},M$ is the mass of the earth $5\mathrm{.}98{10}^{24}($in $kg)$ and $d$ is the distance in meters from the earth's center $($stored in variable distcenter$).$ Note: Assume distance is at least the radius of the earth.
