Vedclass · Answer

(A) The stopping potential is the negative potential at which the photoelectric current becomes zero.From the given graph,the two stopping potentials are $-2 \ V$ and $-4 \ V$.The magnitude of the stopping potential is given by $|V_s|$.Comparing the magnitudes: $|-4 \ V| = 4 \ V$ and $|-2 \ V| = 2 \ V$.Therefore,the maximum value of the stopping potential is $4 \ V$ (in magnitude),which corresponds to the potential value of $-4 \ V$.

The maximum value of the stopping potential in the following diagram is .......... $V$.
