Compute the approximate acceleration of gravity for an object above the Earth's surface, assigning accel_gravity with the result. The expression for the acceleration of gravity is: (G * M) / (d^2), where G is the gravitational constant 6.673 x 10^-11, M is the mass of the Earth 5.98 x 10^24 (in kg), and d is the distance in meters from the Earth's center (stored in variable dist_center). Sample output with input: 6.3782e6 (100 m above the Earth's surface at the equator) Acceleration of gravity: 9.81 See How to Use zyBooks for info on how our automated program grader works. 474696.3774982.qx3zqy7 1 G = 6.673e-11 2 M = 5.98e24 3 accel_gravity = 0.0 4 5 dist_center = float(input()) 6 7 "Your solution goes here" 8 9 print(f'Acceleration of gravity: {accel_gravity:.2f}') 1 test passed All tests passed
