The Coulomb Force in the Classical Sense Is Understood in Terms

question 6

Multiple Choice

The Coulomb force in the classical sense is understood in terms of electric fields. However, in quantum mechanics, the Coulomb force is described in terms of exchange of virtual photons between the charged particles. Why doesn't the creation of the virtual photons violate the principle of conservation of energy?

• A) This is because in quantum mechanics energy is not conserved.
• B) The uncertainty principle, allows photons to be created provided they are absorbed within the time interval \(\Delta\)t.
• C) The photons do not have any energy since they are massless.
• D) The virtual photons are not real photons and hence do not carry any energy.
• E) None of these is correct.
