Potential difference between two given points 5, cm apart, is 20V. What is the value of electric field?

How is potential difference between two points expressed?

What is the phase difference between two points on a wavefront?

Define potential difference between two points in an electric field. Derive the relationship between the electric field and the potential difference.

In an electric field the work done in bringing a 2 coulomb charge from infinity to a point a is 10 joules and in bringing the same charge to some another point B is 20 joule find the potential difference between two points A and B what would be the work done if the same charge is brought directly from A to B.

What is the potential difference between two points in the electric field? Name its SI unit.
