According to special relativity, as the mass approaches the speed of light it increases infinitely, so how do photons have almost negligible mass when they should have infinite mass?
Answers
Answer:As an object approaches the speed of light, the object's mass becomes infinite and so does the energy required to move it. That means it is impossible for any matter to go faster than light travels.

Answer:
According to the special theory of relativity, if the speed of any object reaches near the speed of light then its mass increases and at the speed of light becomes infinite, why is the mass of an electron negligible?
Explanation:
The problem is with the function which represent the variation of mass of an object with its velocity.
If the object moves with 99.99% of speed of light, its mass increases to 70 times of its rest mass.
However if its speed increases from 99.99% to 99.9999%, its mass increases to nearly 700 times.
Therefore for particles like electrons, even moving at 0.999999 times the speed of light, increases its mass to something comparable to mass of proton. (nearly 2.5 times smaller than proton)
Its not at all negligible if you are able to speed them up to infinitesimally close to speed of light.
