The stopping potential in an experiment on a photo electric effect is 1.5 V. What is the maximum kinetic energy of the photoelectrons emitted?

Explanation

To solve the problem of finding the maximum kinetic energy of the photoelectrons emitted when the stopping potential is given, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Stopping Potential**:
The stopping potential (V₀) is the potential difference needed to stop the most energetic photoelectrons emitted from a material when it is illuminated by light. The maximum kinetic energy (KE) of the photoelectrons can be calculated using the formula:
\[
KE = e \cdot V₀
