Homework Statement
If I have a 24 volt power supply.The positive lead is attached to a disk and the negative lead is attached to another. The disks are separated by about 24 cm. The disks are on a sheet of carbon impregnated paper. Is the charge on the disk 24 volts?
I am trying to determine the electric field strength at a point directly in the middle of the two disks.
E= 2*8.99x10^9*q/r^2
but I am not sure what the charge is on the sphere.
