A red blood cell typically carries an excess charge of about –2.5 × 10–12 C distributed uniformly over its surface. The red blood cells can be modeled as spheres approximately 7.0 μm in diameter and with a mass of 9.0 × 10–14 kg. How many excess electrons does a typical red blood cell have? Does the mass of the extra electrons appreciably affect the mass of the cell? To find out, calculate the ratio of the mass of the extra...

Two red blood cells each have a mass of 9.0×10-14 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...

A model of a red blood cell portrays the cell as a spherical capacitor, a positively charged liquid sphere of surface area A separated from the surrounding negatively charged fluid by a membrane of thickness t. Tiny electrodes introduced into the interior of the cell show a potential difference of 100 mV across the membrane. The membrane's thickness is estimated to be 95 nm and has a dielectric constant of 5.00 (a) If an average red blood cell has a...
