Two red blood cells each have a mass of 6.85×10−14 kg and carry a negative charge spread uniformly over their surfaces. The repulsion arising from the excess charge prevents the cells from clumping together. Once cell carries −1.60 pC of charge and the other −2.70 pC , and each cell can be modeled as a sphere 7.40 μm in diameter. What minimum relative speed ? would the red blood cells need when very far away from each other to get close enough to just touch? Ignore viscous drag from the surrounding liquid. v= ? m/s

What is the magnitude of the maximum acceleration ?max of each cell? amax= ? m/s^2
