Solve the following questions given below:

Question 1: What is Newton's law of universal gravitation?

Question 2: What is the force of gravity? Where is it strongest? Is there any gravity on the moon?

Question 3: What is the gravitational force on the moon dependent on? Planets A and B have identical masses but the distance between planet A and the earth is three times the distance between planet B and the earth. How does the weight of an object on A compare to the weight of the object on B?

I need help to solve the above question.
