What will happen to the mass of electron if it travels with velocity of light ?

How many times does the relativistic mass of a particle whose velocity differs from the velocity of light by 0.010% exceed its rest mass?

In a nuclear physics experiment, electrons are to be accelerated so as to have de-Broglie wavelength of the order of the diameter of a heavy nucleus (~​10^(–14) m) . Determine the momentum of the electron needed to make the wavelength of electrons equal to diameter. Use the classical formula for momentum, p = m_(0) v to determine the speed of electrons. Is this speed permissible? Now use the relativistic mass of the electrons in the expression of momentum to find the speed of electrons. Relativistic mass is given by m = (m_(0))/(sqrt(1-v^(2)//c^(2))) . Where m_(0) is rest mass and v is speed of the particle.

Calculate the momentum of electron moving with 1//3 3rd velocity of light .

If I_(0) is the threshold wavelength for photoelectric emission, 1 the wavelength of light falling on the surface of a metal and m is the mass of the electron, then the velocity of ejected electron is given by
