I am trying to build a rotational transformation matrix both for counterclockwise and clockwise angles.
The first matrix in the picture is for counterclockwise angles and the second one for clockwise angles. The first matrix I built corresponds to the one given in my linear algebra book so it...
I am given a continuous charge problem in which there is a non-conducting wire of legnth L lying along the y-axis and I am required to calculate the electric field at any point along the x-axis.
I know how to compute the electric field of a continuous charge distribution at a given point, but...
