A long round cylinderical made of uniform dielectric is placed in a uniform electric field of strength `E_(0)`. The axis of the cylinder is perpendicular to vector `E_(0)`. The axis of the cylinder is perpendiucular to vector `E_(0)`. Under these conditions the dielectrics becomes polarized unifromly. making use of the result obtained in the foregoing probem, find the electric field strength `E` is the cylinder and the polarization `P` of the distance whose permittivity is equal to `epsilon`.
