The maximum kinetic energy of electrons in a photocell is 5.5 eV. Calculate the stopping potential .

Explanation

To solve the problem of calculating the stopping potential given the maximum kinetic energy of electrons in a photocell, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between kinetic energy and stopping potential**:
The maximum kinetic energy (K.E.) of the electrons emitted from the photocell is related to the stopping potential (V_s) by the equation:
\[
K.E. = e \cdot V_s
