Flux density and Divergence of Electric field

Click For Summary
Flux density is defined as the amount of electric flux passing through a unit area, while divergence measures the rate at which electric field lines spread out from a point in space. The discussion clarifies that flux density can be understood as electric field per unit area vector. Divergence is specifically defined as flux per unit volume, indicating a distinction between the two concepts. Overall, the participants agree that flux density and the divergence of the electric field are different quantities.

Homework Statement
Is flux density same as divergence of electric field
Relevant Equations
Div E = (lim as V tends to zero) of (1/V) E*dS
V is volume
I think Flux density is flux/Volume.
Or is it flux/ Area
Please be kind to help
 
Physics news on Phys.org
Divergence is defined as flux per unit volume.
 
Thanks a lot, Gordianus!

I think flux density is electric field / unit area vector...
So flux density and divergence of E are different,right?

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
