Question

A charged capacitor is made of two concentric cylinders or radii r1 and r2. The region between the cylindrical plates is filled with a medium of dielectric constant K the displacement vector (D) at a distance (r) (r1 less than r less than r2)
a) is independent of r
b) varies as lnr
c) is Proptional to r
d) varies as 1/r​

Answer 1

Answer:

a)is independent of r as dielectric constant K does not depent on distance r
