question mark

Calculate maximum voltage that coaxial cable can have without corona effect. Radius of conductor is a=3mm, c=12mm. Cable has two concentric layers of dielectrics which are divided by radius b=6mm. Ɛr1=5, ES1=400kV/cm, Ɛr2=8, Es2=100kV/cm.
Result:
Umax=108,13kV
Could someone help?
Thanks for replies.
