\f(14%) Problem 6: Apatallelplate capacitor with plate maxi, plate separation 11 and a capacitance of C9 = 15 [E in the air. Now a dielectric medium with dielectric constant K = 3.25 is inserted into Iheplajzes. First, the medium occupies all the space between the plates (see Figure 21), and the capacitance is Cf. 1n the second case= it occupies upper halfspace between the two plates (see Figure b). The capacitance is C 3. dIW MID. MID. I (a) | _|_ (b) /
