Pick the correct statement about electron and photon:
Light of wavelength 180 nm ejects photoelectrons from a metal plate of work function 2 eV. If a magnetic field of 5 × 10⁻³ T is applied parallel to the plate, the radius of the path followed by electrons ejected normally with maximum energy is:
If the energy of a photon is 10 eV, its momentum is:
