The capacitance of a parallel plate capacitor can be altered by dragging (drag from the middle) a conducting block in between the two plates (charge given in mC and position given in centimeters). The light red and light blue circles represent the position of the charge on the conductor.
What is the ratio of the new capacitance to the old capacitance? Note: There is a 1-5% intrinsic error in the calculation of charge. Start
