Which particle is listed as the carrier of the electromagnetic force?
AThe photon
BThe gluon
CThe graviton
DThe Z boson
Answer & Solution
Correct answer: A. The photon
1. The basic forces are thought to act through the exchange of microscopic carrier particles.
2. Photons are the carrier particles of the electromagnetic force.
3. The graviton is the proposed carrier of the gravitational force and has not yet been observed.
4. Gluons carry the strong nuclear force, and the W and Z bosons carry the weak nuclear force.
