Capacitor Problem 9.4.4

 

Description

Click-drag the dielectric block into the capacitor (charge given in mC and position given in centimeters).  Observe how the electric field and the charge on the capacitor and the dielectric change when you move the dielectric. The light red and light blue circles represent the position of the charge on the dielectric. 

Question

 What is the dielectric constant of the slab? You can measure the voltage and the electric field at any point by click-dragging.  Note: There is a 1-5% intrinsic error in the calculation of charge. Start

Answer

 2.4.
