MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An air-filled capacitor is made from two flat parallel plates 1.4 mm apart. The inside area of each plate is 9.6 cm?. a) What is the capacitance of this set of plates (in PF)? 84960000001 X PF (b) If the region between the plates is filled with a material whose dielectric constant is 5.6, what is the new capacitance (in PF)? 47577600001 X PF Additional Materials Reading Submit Answer 17. [-/4 Points] DETAILS OSUNIPHYS1 25.4.P.053. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A parallel-plate capacitor has charge of magnitude 9.90 JC on each plate and capacitance 2.60 UF when there is air between the plates. The plates are separated by 1.70 mm. With the charge on the plates kept constant, a dielectric with x = 7 is inserted between the plates, completely filling the volume between the plates. (Enter the magnitudes.) (a) What is the potential difference between the plates of the capacitor (in V) before and after th ric has been inserted? before after (b) What is the electrical field at the point midway between the plates (in V/m) before and after the dielectric is inserted? before V/m
