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.

i think this question is that which one of following has no mass? b/c photon has no mass
Thanks dear Waqas for correction. title updated
Plz sir mention which type of proton which are in rest or motion .proton is massless in rest other wise moving which have mass
Photon not proton.
photon is a massless
Thanks
ELECTEON, PROTON NEUTRON ALL HAVE MASS ONLY ONE QUANTITY THAT HAS NOT MASS THAT IS ONLY PHOTON .YU MADE MIStake .
Thanks for correction.
Photon is mass less
Thanks dear Zulqarnain khan for correction.

Thanks
the photon is a massless particle.

photon has no mass so kindly correct this question
thanks. corrected
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.
Thanks dear Zia. updated now
This question is wrong, plz do correct
It should be massless…
you are right. question is updated now. Thanks dear Asghar ali
Photon has no mass but other all options have mass.
updated. thanks
Photon is mass-less
Thanks Dear Naila for correction.
