## Electric Field due to Disk of Charge

This is the formula for calculating the value of electric field due to a disk of charge. The value thus obtained is measured in Newtons/Coulomb. Th values needed for the formula are the Charge per unit area, the distance to the charge and the radius of the ring which is causing the effect.

## $\frac{q}{8.85*{10}^{-12}}\left[1-\frac{z}{\sqrt{{z}^{2}+{r}^{2}}}\right]$

The values required are q = charge per unit area, z = distance to charge and r = radius of ring
