Compute the acceleration of gravity for a given distance from the earths centef, distCenter, assigning the resuils to accelGravity The expression for the acceleration of gravity is (GM)/(d), where G is the gravitational constant 6.6731011,M is the mass of the earth 5981024( in kg ) and d is the distance in meters from the earthis center (stored in variable distCenter) Note Assume distance is at least the radius of the earth See How to Uke zveoks for info on how out automated program grader works: 1 *include ciostream using nanespace std; Int main() ( double 06.613e11; double H5.98e - 5 ; double accelGravity: double distcenter: cin or distcenter: 12. y.
