How to determine electric field? −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.
Is it harder to play bass or guitar? Physically speaking, the bass is harder to handle than a guitar. It has a longer neck, thicker and heavier strings and requires more finger strength to fret the notes correctly. The bass is also a weightier instrument overall and some musicians find it more difficult (especially on their backs) to play.

Why the electric field strength is not uniform?
The field is considered to be uniform at the center of the plates, but varies close to the edge of the plates. The strength of the field depends on the potential difference applied to the plates and the distance by which they are separated. A higher potential difference or voltage results in a stronger electric field.
