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 find the maximum kinetic energy of the photoelectrons emitted in a photoelectric effect experiment with a stopping potential of 1.5 V, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Stopping Potential**: The stopping potential (V) is the potential difference needed to stop the emitted photoelectrons. It is directly related to the maximum kinetic energy (KE_max) of the photoelectrons.

2. **Formula for Maximum Kinetic Energy**: The maximum kinetic energy of the photoelectrons can be expressed as:
\[
