Defining Flux in the Context of Electric Fields

[nslinker]

A 124 cm diameter loop is rotated in a uniform electric field until the position of the maximum electric flux is found. The flux in this position is measured to be 6.33 x 10⁵.
What is the electric field strength?

Hi nslinker!

What is the definition of flux?

 

[nslinker]

Even though an electric field doesn't actually "flow," I think of it as the flow of electric field vectors, either inward or outward.

After reading it, I still don't know how to get to the correct equation, whether it's just plug-and-chug or if I have to integrate.

It's a uniform electric field …

so integrating it is just multiplying.

So, there is no integration involved, just multiplication?

grrr … get on with it!

 

[nslinker]

so just 1.24 m x (6.33 x 10 ^5)?

Why do you think it's that?

Start with the following question (which you never answered):
