Answer:
Explanation:
We know from Newton's second law that

Now, Newton's law of universal gravitation says

where m = mass of object 1, M = mass of object 2, and r = distance between the objects. '
Now, equating the two equations above gives

Now, dividing both sides by m gives

This is the value of the acceleration due to gravity due to an object of mass M at a distance r away from another object.
Now, near earth, the above equation gives us a = g = 9.8 m/s^2. This can be obtained by substituting M = 5.97 * 10^24 kg, r = earth radius = 6378 km, and G = 6.67 * 10^ -11.








which when rounded to the nearest tenth gives
