lanedance said:by the way what do you mean by this?
To calculate the electric field E^pho in cylindrical coordinates, you can use the formula E^pho = (1/r) * ∂φ/∂z , where r is the distance from the point of interest to the z-axis and φ is the angle measured from the x-axis to the point.
The units for electric field E^pho in cylindrical coordinates are volts per meter (V/m).
Yes, the electric field E^pho can be negative in cylindrical coordinates. A negative value indicates that the direction of the electric field is in the opposite direction of the positive axis.
To convert from Cartesian coordinates (x,y,z) to cylindrical coordinates (r,φ,z), you can use the following formulas: r = √(x^2 + y^2), φ = arctan(y/x), and z = z.
Calculating the electric field E^pho in cylindrical coordinates can be used in various real-world applications such as analyzing the electric field around a cylindrical object, designing cylindrical capacitors, and determining the electric field in a cylindrical wire carrying current.
