Protons and singly ionized atoms of U to the power of 235 end exponent & U to the power of 238 end exponent are passed in turn (which means one after the other and not at the same time) through a velocity selector and then enter a uniform magnetic field. The protons describe semicircles of radius 10 mm. The separation between the ions of U to the power of 235 end exponent and U to the power of 238 end exponent after describing semicircle is given by

In a historical experiment to determine Planck’s constant, a metal surface was irradiated with light of different wavelengths. The emitted photoelectron energies were measured by applying a stopping potential. The relevant data for the wavelength (mu) of incident light and the corresponding stopping potential (V subscript 0 end subscript ) are given below:

Given that c equals 3 cross times 108 m s to the power of negative 1 end exponent text  and  end text e equals 1.6 cross times 10 to the power of negative 19 end exponent C, Planck’s constant (in units of J s) found from such an experiment is
