From a homogeneous and isotropic dielectric material of dielectric constant ?r, a small volume element is taken out creating a cavity. The field can be kept homogeneous if Di. (i.e., electric flux density inside the cavity) and D0 (i.e., electric flux density outside the cavity) are such that
Options
A. D0 = Di
B.
C.
D. either (a) or (b)
Correct Answer
Explanation
Since the field is homogeneous .
