Question

2. Newton's law of universal gravitation states that the force of gravity between two bodies is proportional to the product of the two masses (m1 and m2) and inversely proportional to the square of their separation (r). a) If we cut the separation in half, how would the force of gravity change? b) If we doubled the separation, how would the force of gravity change? c) If we doubled one of the masses, how would the force of gravity change? d) If we doubled both of the masses, how would the force of gravity change?

Step 1

If we cut the separation in half, the force of gravity would be inversely proportional to the square of the new separation (r/2). So, the new force of gravity would be: $$F' = \frac{Gm_1m_2}{(r/2)^2} = \frac{Gm_1m_2}{(r^2/4)} = 4\frac{Gm_1m_2}{r^2} = 4F$$ So, Show more…
