1. An electron in the hydrogen atom jumps from excited state n to the ground state. the wavelength so emitted illuminates a photosensitive material having work function 2.75 eV. if the stopping potential of the photoelectron is 10 V, then the value of n is

Here is the process,pls understand it carefully.
