Which of the following statements about the nature of electrical charge is FALSE? Positive-positive or negative-negative charges
repel each other. Positive and negative charges cancel each other so that a proton and electron, when paired, are charge neutral. Electrical charge is a fundamental property of protons and electrons. Positive and negative electrical charges attract each other. All of the above statements are true.
All matter is composed of atoms of which have subatomic particles. Subatomic particles are electrons, protons and neutrons. Each particle has electric charges.
Electrons have a negative charge, protons have a positive charge and neutrons have zero charge.
Between two nearby charges initially at rest, a type of forces, called electrostatic, is always established in such a way that, if the charged particles are small enough so that they can be considered punctual, the following conditions are met:
The force established between the two has a direction that coincides with an imaginary straight line that joins the two charges.
The force exerted on one load points towards the other when the two have different signs, one positive and the other negative. (attractive force).
The sense of force is directed to the opposite side of the charge when both have the same sign (repulsive force).
Avoid downed power lines and stay away from buildings and bridges from which heavy objects might fall during an aftershock. Stay away until local officials tell you it is safe. A tsunami is a series of waves that may continue for hours. Do not assume that after one wave the danger is over.
