Understanding Electron Repulsion and Photons

What happens when two electrons are placed near each other?

• They attract each other.

• They repel each other.

• They remain stationary.

• They combine to form a new particle.

What is the role of a photon in the interaction between two electrons?

• It attracts the electrons.

• It carries the electromagnetic force.

• It neutralises the charge of the electrons.

• It converts electrons into protons.

What is the term used to describe particles like photons that mediate forces between other particles?

• Leptons

• Quarks

• Bosons

• Fermions

In the context of the interaction between two electrons, what does the exchange of a photon signify?

• The electrons are merging.

• The electrons are communicating their presence to each other.

• The electrons are losing energy.

• The electrons are gaining mass.
