Chapter 24, Problem 1PQ

The terms electrostatic force and electrostatic field may sound alike. To help keep them straight, identify and write down the standard symbol and SI units for each one. Which one requires a source and a subject? Which requires only a source?

To determine

SI units for both electric force and field and which of them requires a source and a subject, and requires only source.

Answer to Problem 1PQ

The SI units for electric force and field are N and $\text{N}/\text{C}$. The electric force requires both the source and subject and the electric field requires only source.

Explanation of Solution

The SI units of the electric force is N (Newton) and for the electric field is N/C (Newton per Coulomb).

The electric force requires both the source and subject whereas; electric field requires only a source.

Conclusion:

Therefore, the SI units of the electric force and field are N and $\text{N}/\text{C}$. The electric force requires both the source and subject and the electric field requires only source.
