Final answer:
The expression p = Pori/r represents the charge distribution throughout a spherical shell. The electric field due to this charge as a function of r can be found using the formula E = k * p/r.
Step-by-step explanation:
The given expression represents the charge distribution throughout a spherical shell. The charge density (p) at a point (r) from the center of the shell can be calculated using the formula: p = Pori/r, where po is a constant.
So, the electric field due to this charge as a function of r can be found using the formula: E = k * p/r, where k is a constant and represents Coulomb's constant. The electric field will vary with the inverse of the distance from the center, becoming weaker as you move farther away.
