Two red blood cells each have a mass of 7.50Γ10β14 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 β1.80 pc of charge and the other β3.30 pc , and each cell can be modeled as a sphere 6.80 ΞΌm 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.
