Solution Summary
The expert determines the kinetic energy of electrons by the incident light by using the stopping potential of 4.0 V.
Solution Preview
When an electron moves against a potential difference V (from +ve potential towards -ve potential), it does negative work against the force acting on it (i.e. the electron moves in a direction opposite to the force acting on it and in the process loses its kinetic energy). The ...
