Red blood cells can be modeled as spheres of 7.03 µm diameter with –2.55 × 10-12 C excess charge uniformly distributed over the surface. Find the electric field at the following locations, with radially outward defined as the positive direction and radially inward defined as the negative direction. The permittivity of free space eo is 8.85 × 10-12 C/ (V-m). What is the electric field Éj inside the cell at a distance of 3.25 µm from the center?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
Please help solve for E2
Given:
The diameter of the sphere = 7.03 x 10-6 m
Charge on the sphere = -2.55 x 10-12 C
Permittivity of free space = 8.85 x 10-12 C/Vm
Electric field inside the cell at some distance= ?
Electric field just inside the surface of the cell = ?
