Assume that a red blood cell is spherical with a radius of 4.0 ×10^−6 m and with a wall thickness of 9.3 ×10^−8 m. The dielectric constant of the membrane is about 5.0. The potential difference across the membrane is 0.080 V. (Capacitance of cell is 9.6*10^-14F) Determine the positive charge on the outside and the equal-magnitude negative charge inside. Express your answer with the appropriate units.
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
