Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Two red blood cells each have a mass of 9.0x 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. One cell carries -2.50 pC of charge and the other -3.70 pC,
and each cell can be modeled as a sphere 7.5 μm in diameter.
1) What speed would they need when very far away from each
other to get close enough to just touch? Assume that there is no
viscous drag from any of the surrounding liquid. (Express your
answer to two significant figures.)
