the stopping potential in an experiment of photon is 2v what is the maximum kinetic energy of photoelectrons emitted?
Asked by vasturushi | 28 Feb, 2018, 12:49: PM
answered-by-expert Expert Answer
I assume the stopping potential given in the question is 2 eV

The relation connecting the stopping potential and maximum kinetic energy is given by
 
Kmax = eVo ; Kmax is the maximum kinetic energy, Vo is stopping potential and e is electronic charge.
 
Kmax = 2 eV = 2 × 1.602 × 10-19 Joules = 3.2 × 10-19 Joules

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
