Question 2

The force of gravity is the only one of the four forces felt on very large size scales. Which of the following best explains why the other forces don't play a major role on large scales?

A) The other three forces are all very short in range, and cannot be felt over large distances.
B) The strong and weak forces act only on very small scales, and large objects tend to be electrically neutral and therefore don't feel an electromagnetic force.
C) Gravity is by far the strongest force, so it simply dominates on large size scales.
D) Effects of the strong and weak forces tend to cancel out effects of the electromagnetic force on large scales.
