stopping potential depends upon what factors?? Share with your friends Share 0 Sanjay Singh answered this Dear student If light of frequency f is incident on the metal surface of work function W than maximum kinetic energy with which electron comes out the metal surface isKmax=hf-WStopping potential is the minimum value of potential required to stop photoelectric current.Now if the electron is made to pass through a potential V volt such that it creates an electric field that applies a force opposite to the direction of its motion in the experimental tube than thiselectric field does negative work on it and hence decrease its kinetic energy. magnitude of work done by electric field when electron passes through a potential difference of V volt=e×VIf this work done decreases the maximum kinetic energy of electron to zero than this potential V is called stopping potential.Kmax=e×(stopping potential)hf-W=e×(stopping potential)hf-W=e×VsVs=hf-WeSo stopping potential depends on frequency of incident radiation and work function of metal which depends on nature of material of metal surfaceRegards 3 View Full Answer Shivam Swami answered this The stopping potential depends on the kinetic energy of the electrons, which is affected only by the frequency of incoming light and not by its intensity. regards 5 Deepesh Mishra answered this Stopping Potential depends on Frequency of Incident Radiation. 0
