Correct statements (check all that apply):

- The gravitational force has an infinite reach. — True.
- The electrical force has an infinite reach. — True.
- The gravitational force is inversely proportional to the square of the distance. — True.
- The electrical force is inversely proportional to the square of the distance. — True.

Incorrect:
- The gravitational force is inversely proportional to the distance. — False (it's ∝ 1/r^2).
- The electrical force is inversely proportional to the distance. — False (it's ∝ 1/r^2).

Brief note: both Newtonian gravity and Coulomb's law fall off as 1/r^2 (so they never strictly go to zero), although electrical effects can be effectively screened in matter (Debye screening) while gravity cannot be shielded.
