Name the anti-particle of an electron.

Name the fundamental particle of an atom that has highest value for its e/m

Who demonstrated the particle property of an electron?

A particle is moving three times as fast as an electron. The ratio of the de Broglie wavelength of the particle to that of the electron is 1.813 xx 10^(-4) . Calculate the particle’s mass and identify the particle.

Compare the sub-atomic particles electron, proton and neutron (AS_(1))

Name the species which has no electron.

Calculate the wavelength of an electron in a 10 MeV particle accelerator (1 MeV = 10^6eV) .

Particles emitted from some radioactive material are observed to be deflected in a magnetic field (i) the particles may be electrons (ii) the particles may be protons (iii) the particles may be neutrons (iv) the particles may be hydrogen atoms. State if
