To calculate the electric field due to a uniformly charged disk at a point on its axis, you can use the following formula:

E = (σ / 2ε₀) * (1 - x / √(x² + R²))

Where:

- E is the electric field
- σ is the surface charge density
- ε₀ is the electric constant (permittivity of free space)
- x is the distance from the center of the disk to the point on the axis
- R is the radius of the disk

For points at the center of the disk (x = 0), the formula simplifies to:

E = σ / 2ε₀

When the radius of the disk is much larger than the distance (R >> x), the electric field approaches:

E = σ / 2ε₀

This formula is derived by integrating the contributions of infinitesimal rings that make up the disk.
