Noting the connection between work and potential W -qDelta V as in the last section we can obtain the following result. I have two points in space on the surface of the earth represented using spherical coordinates in this case there is no z axis since both are assumed to be at the same height. Calculating the Distance From a Point To a Line The distance from a point to a line is the length of the shortest path between that point and the place on the line.
Since Coulombs law applies to point charges the distance d in the equation is the distance between the centers of charge for both objects not the distance between.
Know the distance formula. The formula of distance between two points is P x 1 y 1 and Q x 2 y 2 is given by. The distance formula is derived from the Pythagorean theorem. Take the coordinates of two points you want to find the distance between.
