In the Cell Stem Cell study, Eggan and postdoctoral fellow Evangelos Kiskinis led an effort to make stem cell lines from two women with ALS who have SOD1 mutations in order to compare human biology and mouse biology.
Felec = k q1q2r2. In the given equation the Felec is the electrical force, q1 and q2 are the charges on two objects while ârâ is the radius between the objects. K is the proportionality constant that makes the units of force consistent with the units of charges.
This force is used in the formal definition of the ampere, which states that the ampere is the constant current that will produce an attractive force of 2 Ã 10â7 newtons per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum.
