Electric field on the axis of a system (-q, + q) - Corrected exercises of electromagnetism
Electric field on the axis of a (- q + q).
we have two point electrical charges carried by a x'Ox axis: - q on A (-a) and +q on B (+a) with q positive.
1. Express the electric field created by M (x) by the distribution in space, M belonging to the x'Ox axis.
2. Represent Ex in terms of x
