What are the charge and mass of an electron?

A stream of electrons from a heated filament was passed between two charged plates kept at a potential different V esu. If e and m are charge and mass of an electron, respectively, then the value of h//lamda (where lamda is wavelength associated with electron wave) is given by-

What is the value of charge of an electron?

What is the charge of an electron, proton and a neutron ?

Electrons starting from rest and passing through a potential difference of 60 kV are found to acquire a velocity of 1.46 xx 10^(10) cm cdot s^(-1) . Calculate the ratio of charge to the mass of an electron.
