Problem: A thunderstorm may be considered as dipole with a charge -q at cloud level, h and its image in the Earths conducting surface, +q at a depth of -h. The breakdown electric, filed, which allows an electric discharge to occur is near 3000v/m the ground and at altitudes above could. If q=200C and h=6km.
Part A: Calculate the range of heights where discharges are likely?
Rework your solution from the starting and check each step carefully. Thank you.
