The figure shows plots of charge versus potential difference for three air-filled spherical capacitors. Radii of capacitors are the following: capacitor 1: R/2 and R, capacitor 2: R/4 and R/2, and capacitor 3: R/3 and 2R/3. Which plot goes with which capacitor? a 9. capacitor 1 - plot a, capacitor 2 - plot b, capacitor 3 - plot c O capacitor 1 - plot c, capacitor 2- plot b, capacitor 3- plot a O capacitor 1 - plot b, capacitor 2- plot c, capacitor 3- plot a O capacitor 1- plot c, capacitor 2 - plot a, capacitor 3- plot b O capacitor 1 - plot a, capacitor 2 - plot c, capacitor 3- plot b
