What is the Susceptibility of a Linear Dielectric Material?

Click For Summary
SUMMARY

The susceptibility of a linear dielectric material can be calculated using the relationship between the electric field in the material and the vacuum field. In this discussion, it was established that the electric field in the material is 38% less than that in a vacuum, leading to the conclusion that the susceptibility, χ(material), is 1.61. This value was derived by taking the ratio of the electric fields and applying the formula P = εχE, where P represents polarization and ε is the permittivity of the material.

Homework Statement


I have a linear dielectric material. The electric field in the material is 38% less than a vacuum field with the same external sources. I need to find the susceptibility of the material?

Homework Equations



I used
P=\epsilon\chi(vacuum)E
P=\epsilon\chi(material).62E

The Attempt at a Solution


i did the ratio of the 2 and i found

\chi(material)= 1.61

is this correct?

I'm not sure what you mean here.. the polarization in vacuum should be zero shouldn't it? What field stays the same when the free charge sources are unchanged? Electric field ? Displacement field? Polarization?
