Homework Statement
Hollow dielectric cylinder, with inner radius a, outer radius b, and height 2h is uniformly polarized by volume. Polarization vector is normal on the bases of a cylinder. Intensity of polarization vector is given, P. The surrounding area is vacuum. Calculate intensity of electric field in center of the cylinder (at point C)
Homework Equations
-Cylindrical geometry
-Polarization vector
The Attempt at a Solution
If approximated, intensity of electric field could be E= -P/ε0 (field between two oppositely charged planes). But, we don't know the exact values for dimensions of a cylinder. Could someone give a hint on this, I am stuck here for a while.
The result should be E= -Ph( 1/(√a2+h2)-1/(√b2+h2)) / ε0
Thanks for replies.
