So I think the equivalent question is “at what speed does an electron’s energy become twice its mass?” as γ=1/1−v2/c2−−−−−−−−√=E/mc2. Take the square root again and you get the relevant speed as a fraction of c.
Q. At what speed will the mass of a body be 20 percent more than its rest mass?
Therefore, for a particle’s relativistic mass to be 20% higher than rest mass, its velocity must be . In the equation of relativistic mass, if the velocity of an object becomes equal to the speed of light, then its mass becomes infinite.

Q. At what speed an electron will have to move in order to double its rest mass?
Calculating it out further it gives a speed of 2.598 •10^8 m/s. This tells you that for any mass, whether a proton, or a neutrino, or a 1,000,000 Kg giant spaceship, for its mass to be doubled the mass would have to reach 0.866c in speed or a speed of 2.598 • 10^8 m/s…
Q. When the mass of an electron becomes equal to?
When the mass of an electron becomes equal to thrice its rest mass, its speed is.
Q. Why is the rest mass of a photon zero?
The rest mass is the mass of a particle (in our case the photon) as measured by an observer who sees the particle still and with zero speed. Thus comes the term REST mass. But according to special relativity, light ALWAYS travels with the light speed c, and is NEVER at rest. And so it has zero REST mass.
Q. At what speed a particle moves if its mass is equal to 4 times its rest mass?
constant speed otherwise Einsteins General Relativity will work here. According to your question , => Lorentz factor is 4.
Q. Why does mass becomes infinite at the speed of light?
Near the speed of light, the mass is so high that it reaches infinity, and would require infinite energy to move it, thus capping how fast an object can move. The only reason light moves at the speed it does is because photons, the quantum particles that make up light, have a mass of zero.
Q. At what speed will the mass of a body is 2.25 times its rest mass?
If ‘mass’ is defined as “how much momentum you have to spend to increase v by one unit”, then the ‘mass’ does increase — it would take an infinite amount of momentum to reach the speed of light.
Q. What will be the velocity of light having mass double than its rest mass?
The correct option is (C) {(√3c) / 2}.
Q. What is velocity of particle whose mass is double that of rest mass?
As per the question m’ = 2m. We are asked to calculate the speed of the particle. As per Einstein’s theory of relativity, Here v is the velocity of the body and c is the velocity of light.
Q. What should be velocity of object so that mass becomes twice of its rest mass?
So a proton observed at % the speed of light will have an equal amount of rest energy to kinetic energy. That is about m/s. so v=0.866 c is the velocity of the particle which double its rest mass.
Q. What happens to the kinetic energy of a particle when its relativistic mass doubles?
For starters, whereas the rest mass of an object is an intrinsic property, kinetic energy is not: it depends on the observer. Either way, doubling the “relativistic mass” means doubling the total energy, as the proportionality factor between the two, the vacuum speed of light squared, remains the same.
Q. At what velocity the kinetic energy of a particle is equal to the rest mass energy?
When the kinetic energy is equal to mc2, the object’s velocity will be about 87% of the speed of light.
Q. What is the velocity of kinetic energy?
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
