The electric field from a very long charged wire is ( , toward the wire). What is the charge (in ) on a -cm-long segment of the wire
The charge on a segment of the wire is .
Linear charge density,
Given segment , the linear charge density will be:
Rearrange the value,
Because the electric field is oriented toward the wire, the charge on the wire will have a negative charge.
You’ve been assigned the task of determining the magnitude and direction of the electric field at a point in space. Give a step-by-step procedure of how you will do so. List any objects you will use, any measurements you will make, and any calculations you will need to perform. Make sure that your measurements do not disturb the charges that are creating the field.
