The correct answer is
Electric charges produce electric fields.
In fact, electric fields are produced by electric charges. For instance, the electric field produced by a single-point charge is radial, and its intensity decreases as the inverse of the square of the distance from the charge, according to:
where k is the Coulomb's constant, q is the magnitude of the charge and r is the distance from the charge. If the charge is positive, the electric field points away from the charge; if the charge is negative, the electric field points toward the charge.
Answer:
In a nutshell, units of A and B are and
, respectively.
Explanation:
From Dimensional Analysis we understand that and
have length units (
) and
have time units (
). Then, we get that:
(Eq. 1)
(Eq. 2)
Now we finally clear each constant:
In a nutshell, units of A and B are and
, respectively.
