The permittivity of water at this temperature is 7.07x10-10 C2/N-m2. 2. Gold Member. Of course! Lets raise the If the charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero. In the analysis presented in this paper, we have kept the streamer branching distance constant as the streamer extends outwards and into the low field region. When it occurs between two separate clouds, it is known as cloud-to-cloud (CC) or inter-cloud lightning; when it occurs between areas of differing electric potential within a single cloud, it is known as intra-cloud (IC) lightning.
