Consider two parallel-plate capacitors identical in shape, one aligned so that the plates are horizontal (Figure 1) , and the other with the plates vertical (Figure 2) .
1. The horizontal capacitor is filled halfway with a material that has dielectric constant 2.15. What is the new capacitance of the capacitor?2. The vertical capacitor is filled halfway with a material that has dielectric constant 2.15. What is the new capacitance of the capacitor?
