Is E constant in simple Gaussian diagram?

[ZedCar]

Homework Statement

If you have a simple Gaussian diagram of spherical shape, and arrows pointing out from the centre indicating [E] how do you know if [E] is constant or if it varies?

Is it because the arrows are of slightly different lengths? (Though all eminating from the centre and going out past the circumference.) Does this indicate variation?

Or would variation be indicated by arrows in different areas being more tightly together than other areas?

Thank you.

It depends upon what convention was used when the drawing was made.

Is there a standard convention for indicating whether [E] is constant or varies in a simple spherical Gaussian diagram?

Can you scan the diagram and post the image?

Can you scan the diagram and post the image?

Unfortunately I don't have a scanner to hand.

But if I can describe it, it's simply...

A circle with arrows all pointing out from the same point at the circle centre, and all ending once outside the circle. They all seem evenly spaced apart from each other.

However, even though they all end once outside the circle, some of them are slightly longer than others.
