Question

If electric field strength is force per charge, how could one find the force?A. Ohm’s lawB. Coulomb’s lawC. Joule’s lawD. Ampere’s law

Answer 1

`\begin{gathered} F=qE \\ so: \\ E=(F)/(q) \end{gathered}`

If F is the electrostatic force, we can find it using the following formula:

`F=k\cdot(q1\cdot q2)/(r^2)`

Which corresponds to the Coulomb's law

Answer:

B. Coulomb's law
