To find the dynamic mass of an electron moving with a speed of 0.8c, we can use the formula for relativistic mass: \[ m = \frac{m_0}{\sqrt{1 - \frac{v^2}{c^2}}} \] where: - \( m \) is the dynamic (relativistic) mass, ...

The mass of an electron at rest is 9.1 xx10^(-31) kg. the mass of an electron, when it is moving with a speed of 2.4xx10^(8) m/s is (c=3xx10^(8) m//s)

The percentage increase in the rest mass of an electron when it is moving at a speed of 0.6 c where c is the speed of light, is

A famous relation in phyics relates the moving mass m to the rest mass m_(0) of a particle in terms of its speed v and the speed of light c .( This relation first arose as a consequence of the special theory of relativity due to Albert Einstein). A body recalls the relation almost correctly but forgets where to put the constant c . He writes m = (m_(0))/((1- V^(2))^(1//2)) . Guess where to put the missing c .

An electron of mass m_(e) and a proton of mass m_(p) are moving with the same speed. The ratio of their de-Broglie wavelength lamda_(e)//lamda_(p) is

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.

When the mass of an electron becomes equal to thrice its rest mass, its speed is

Calculate the energy in MeV equivalent to the rest mass of an electron . Given that the rest mass of an electron , m=9.1 xx 10^(-31) kg , 1MeV = 1.6 xx 10^(-13) J and speed of light , c= 3 xx 10 ^(8) ms ^(-1) .

A neutron having a mass of 1.67 xx 10^(-27) kg and moving at 10^(8) m//s collides with a deuteron at rest and sticks to it. If the mass of the deuteron is 3.33 xx 10^(-27) kg then the speed of the combination is
