Electric Forces Quiz B

What happens when opposite charges interact?

• They repel each other

• They attract each other

• They have no effect on each other

• They explode

Answer explanation

When opposite charges interact, they attract each other due to the fundamental principle of electromagnetism, which states that opposite charges exert an attractive force on one another.

What occurs when Mr H's dogs bring the opposite poles of their magnets close to each other?

• They attract each other

• They repel each other

• They combine to form a new magnet

• They remain stationary

Answer explanation

Like charges, such as two positive or two negative charges, repel each other due to the electrostatic force. This means they push away from one another rather than attract, combine, or remain stationary.

What happens when like charges interact?

• They attract each other.

• They repel each other.

• They have no effect on each other.

• They combine to form a neutral charge.

Answer explanation

Like charges, such as two positive or two negative charges, repel each other due to the electrostatic force. This is a fundamental principle of electromagnetism.

What is the definition of electric force?

• The attraction between magnets.

• The push or pull between charged objects.

• The force holding atoms together.

• The energy from a battery.

Answer explanation

The correct choice defines electric force as the push or pull between two objects with an electric charge, which is fundamental to understanding how charged particles interact.

What charge does a proton have?

• Negative charge

• Positive charge

• Neutral charge

• No charge

Answer explanation

A proton carries a positive charge, which is fundamental to its identity as a subatomic particle. This distinguishes it from electrons, which have a negative charge, and neutrons, which are neutral.

What charge does an electron have?

• Positive charge

• Neutral charge

• Negative charge

• No charge

Answer explanation

An electron carries a negative charge, which is fundamental to its nature. This negative charge is essential for the formation of atoms and the interactions between charged particles.

What part of the atom has a positive charge?

• Electron

• Neutron

• Proton

• Atom

Answer explanation

The proton is the part of the atom that carries a positive charge. In contrast, electrons have a negative charge, and neutrons are neutral. Therefore, the correct answer is proton.

Which part of the atom is negatively charged?

• Proton

• Neutron

• Electron

• Nucleus

Answer explanation

The part of the atom that has a negative charge is the electron. Electrons orbit the nucleus and are responsible for the negative charge, while protons have a positive charge and neutrons are neutral.

What type of charge do electrons have?

• Positive

• Negative

• Neutral

• No charge

Answer explanation

Electrons carry a negative charge, which is fundamental to their role in electricity and chemical bonding. This distinguishes them from protons, which have a positive charge, and neutrons, which are neutral.

Which particles in the nucleus are considered neutral?

• Protons

• Electrons

• Neutrons

• Positrons

Answer explanation

Neutrons are the neutral particles found in the nucleus of an atom, having no electric charge. In contrast, protons are positively charged, and electrons are negatively charged, while positrons are the antimatter counterparts of electrons.
