Question

   

If Fg is originally 18,434 newtons...

What will Fg become if we double m1 and cut the radius in half?

Answer 1

Doubling m1 doubles Fg as the m1 is in the numerator

Halving the radius multiples Fg by 4, as (1) r is in the denominator (2) r is squared

So putting these together we will multiply Fg by 2 x 4 = 8
