Two red blood cells each have a mass of 9.0 ร 10 โ 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. One cell carries โ2.50 pC of charge and the other โ3.10 pC, and each cell can be modeled as a sphere 7.5 ฮผm in diameter. (a) What speed would they need when very far away from each other to get close enough to just touch? Ignore viscous drag from the surrounding liquid. (b) What is the magnitude of the maximum acceleration of each cell in part (a)?
