Two red blood cells each have a mass of 9.05 10-14 kg andcarry a negative charge spread uniformly over their surfaces. Therepulsion arising from the excess charge prevents the cells fromclumping together. One cell carries -2.10 pC and the other -2.60pC and each cell can be modeled as a sphere 3.75 10-6 m inradius. If the red blood cells start very far apart and movedirectly toward each other with the same speed what initial speedwould each need so that they get close enough to just barely touch?Assume that there is no viscous drag from any of the surroundingliquid.
