HI I dont understand the method of image.
I have this problem:
A uniform charged disk is suspended ( at a distance h) above an infinite conducting plane ( disk is parallel to the plane). The disk carries a charge Q and has a diameter d. Assume d>>h.
1- Calculate the electric field vector near the center and below the disk.
2- Calculate the capacitance of the system using the formula C=Q/V.
3- Calculate the capacitance of the system using the energy formulas.
I tried to draw a picture.
^Y(unit vector direction)
h ( distance between disk and plane)
\\\\\\\\\\\\\\\\\\ (plane) .-----> x(unit vector)
I dont understand the procedure.
please can someone help me?
