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.
The electric field at a given point is defined as the (vectorial) force that would be exerted on a stationary test particle of unit charge by electromagnetic forces (i.e. the Lorentz force). A particle of charge would be subject to a force.
