Two red blood cells each have a mass of 5.50×10−14 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 −2.40 pC of charge and the other −3.50 pC, and each cell can be modeled as a sphere 8.00 μm in diameter.

What minimum relative speed v 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.
