Unformatted text preview: PHYS 102 MIDTERM EXAM 1 Student Name & Surname: 4- Two different dielectrics fill the space between the square
parallel plates of a capacitor with plate separation d; ‘ a- Write the capacitance C in terms of the dielectric
constants K1 , K2, the length of the plate L and the plate separation d1 = d2 = d l 2 , as shown in Figure 4a; (9 pts), b- If a portion of depth L and of width x is cut out from the
dielectric with K2 as shown in Figure 4b, find the new
capacitance, Cnew, (10 pts), c- Write the energy U stored for both casesi if the potential
difference between the plates is V0 . (6 pts). 2.1.1 7:32..
