Capacitor 9.4: Additional Problem 2

 

Description

A capacitor is made out of  a sphere and a spherical shell maintained at a constant potential difference as shown in the animation (charges are given in mC and distances are given in centimeters).  You may click-drag on the inner sphere to resize it. 

Question

 What happens to the capacitance of the system when the inner sphere is resized?  Note: there is a 1-5% intrinsic error in the calculation of charge. Start

Answer

 The capacitance increases/decreases as the inner sphere increases/decreases in radius.
