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: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).

Sample program:

#include

int main(void) {
const double G = 6.673e-11;
const double M = 5.98e24;
double accelGravity = 0.0;
double distCenter = 0.0;

distCenter = 6.38e6;

printf("accelGravity: %lf\n", accelGravity);

return 0;
