`E = (2*k* q )/( L * r )`

Enter a value for all fields

The **Electric Field for a uniform line of charge** is found using the following formula: `E=(2kq)/(Lr)`, where:

- `E` = Electric Field for a uniform line of charge
- `k` = Coulomb's Constant
- `q` = charge
- `L` = unit length
- `r` = distance from line
