  1. Two parallel conducting plates are separated by 5.0 cm5.0\text{ cm}. The variation of electric potential with distance between the plates is shown.
A line graph showing electric potential in kV on the y-axis and distance in cm on the x-axis. The line starts at (0, 20) and goes down to (5.0, 0).
