A. Proton
B. Electron
C. Neutron
D. Photon

the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.

      1. Plz sir mention which type of proton which are in rest or motion .proton is massless in rest other wise moving which have mass

  1. ELECTEON, PROTON NEUTRON ALL HAVE MASS ONLY ONE QUANTITY THAT HAS NOT MASS THAT IS ONLY PHOTON .YU MADE MIStake .

  2. the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.

  3. This question must be like this…

    Which one of the following HAVE NO mass?

    As Photons have no mass. Rest of the particles do have.
