When you take off a wool hat, some of the electrons from your hair transfer to
the hat. When this happens, your hair can stand up on end. Why doesn't
gravity hold your hair down?
A. The distance to the center of Earth is vastly larger than between
the hat and your hair,
B. The electrical field caused by the charged hair disrupts the
gravitational field near your hair
C. The electrostatic force is stronger than the gravitational force
between Earth and your hair,
D. The gravitational force between the hat and your hair opposes
Earth's gravitational force,
