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.
Answer: 0.0267 N. Explanation: The electrostatic force is directly related to the product of the charges and inversely related to the square of the separation distance. Tripling one of the charges would serve to triple the force. Tripling the distance would serve to reduce the force by a factor of nine.
