Two red blood cells each have a mass of 9.05×10^−14kg and carry a negative charge spread uniformly over their surfaces. The repulsion arising from the excess charge prevents the cells from clumping together. One cell carries −2.70pC and the other −3.30 pC, and each cell can be modeled as a sphere 3.75×10^−6m in radius. If the red blood cells start very far apart and move directly toward each other with the same speed, what initial speed would each need so that they get close enough to just barely touch? Assume that there is no viscous drag from any of the surrounding liquid.

initial speed:m/s

What is the maximum acceleration of the cells as they move toward each other and just barely touch?

maximum acceleration:m/s^2

Two particles each have a mass of 5.6 x 10-4 kg. One has a charge of +5.4 x 10-6 C, and the other has a charge of -5.4 x 10-6 C. They are initially held at rest at a distance of 0.72 m apart. Both are then released and accelerate toward each other. How fast is each particle moving when the separation between them is one-third its initial value?
