Which charges attract and which repel?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object.
How do electrical charges attract and repel?
Electric charge is a physical property of particles or objects that causes them to attract or repel each other without touching. Particles that have opposite charges attract each other. Particles that have like charges repel each other. The force of attraction or repulsion is called electric force.
What determines whether an electric force is attractive or repulsive?
The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.
Are attracted to negatively charged particles and repelled from positively charged particles?
Electricity is the behavior of negatively and positively charged particles due to their attraction and repulsion. Like charges (two negatively charged particles or two positively charged particles) repel each other while opposite charges (a positively charged particle and a negatively charged particle) attract.
What happens to the repulsive energy between two like charges when the charges increase?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.
What determines the direction of the electric force between two charges?
The direction of the force vector depends on the sign of the charges. If the charges are the same, the force points away from the other charge. If the charges have different signs, the force points toward the other charge((Figure)).
Why do opposites attract and likes repel?
Electrons have a negative charge and protons have a positive charge, so they attract each other. Another example are positive ions (cations) moving towards cathode and negative ions (anions) moving towards anode in electrolysis. Opposite (unlike) charges attract each other. Same(like) charges repel each other.
