Explain the term permittivity and how this affects force

[skanecfc]

Hey everyone
I just started an engineering course and have been given a few questions but I am struggling with this one as i feel that i have not included all the info that should be there. Can someone tell me briefly what they would explain the term permittivity as and how they think it would affect force

hey skanecfc! welcome to pf!

why not show us the info you have included, so that we can help with suggestions?

I put Coulomb's Law and the formula F=K (Q1Q2 over Resistance Squared)
Where K is a constant and its formula
The electric permittivity and its equation
Absolute permittivity
and lastly i put the reasons why dielectric materials are used in capacitors

have i missed anything?
