This is not a homework question, but I was just wondering, why can't a uniform electric field be described by the formula E=\frac{kq}{r^2} ?

SUMMARY
A uniform electric field cannot be described by the formula E=\frac{kq}{r^2} because this equation represents the electric field generated by a point charge, which varies with distance (r). In contrast, a uniform electric field is characterized by a constant magnitude and direction across a specified region of space, independent of distance. The distinction lies in the nature of the electric field: uniform fields are produced by parallel plate configurations, while E=\frac{kq}{r^2} applies to point charges.
