# Susceptibility dielectric 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?

$$\chi(material)$$= 1.61
