Question

According to Newton's Law of gravitational attraction, what is the dependence of the force on the distance between the masses?

• A. Directly proportional to square of distance
• B. Inversely proportional to square of distance
• C. Directly proportional to fourth power of distance
• D. Inversely proportional to fourth power of distance

Answer 1

Answer:

B. Inversely proportional to square of distance

Newton's law of gravitation states that the force between two particles is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The equation for this is$F \propto {\frac {m_1 m_2}{ r^ 2}} \Rightarrow F = G \frac {Mm}{r ^ 2}$ where G is the gravitational constant.
