A student performs an experiment on photoelectric effect using two materials A and B. A plot of stopping potential (V0)vs frequency (u) is as shown in the figure.
The value of h obtained from the experiment for both A and B respectively is
(Given electric charge of an electron = 1.6 × 10–19 C)
The value of h obtained from the experiment for both A and B respectively is
