Problem 19.04. Gel Electrophoresis is an experimental procedure which can be used toseparate DNA and/or RNA molecules by size. The molecules are placed in a gel thenelectrodes are added to create a potential difference across the gel. The molecules, which arecharged, feel two forces, the electric force due to the presence of the electric field, and a dragforce due to inter-molecular forces.

Two equally charged, 1.00 g spheres are placed with 4.00 cm between their centers. 2 When released, each begins to accelerate at 225 m/s . As the spheres move, do you expect the force between them to increase, decrease or remain the same? Use an equation to justify your reasoning. Calculate the spacing needed between the spheres that would cut the force between them in half.
if the force that a proton exerts on an orbiting electron is F, what is the force that the electron exerts on the proton?. Why?. No explanation, no points.
Shown are the configuration of a gel electrophoresis experiment. Charged plates establish an electric field on a region of gel between the plates. A solution of DNA fragments, which acquire a negative charge in solution, is analyzed by using an electric field to drive the fragments through the gel. A drag force opposes the motion, causing the fragments to move at a constant speed. Larger fragments move more slowly, so the fragments separate by size to give a “fingerprint” of the sample. In the system shown , the electric field is directed to the _____; the DNA fragments move to the _____.A. right, right B. right, leftC. left, right D. left, left
