Coulombs law and space-time

  1. Apr 17, 2014 #1
    Im reading about Coulombs law in my textbook.

    It states that:

    "The forces between to charged particles are proportional with the charges Q1 and Q2, and inversely proportional with the square of the distance r between them.


    The forces acts along the straight line between the particles"

    Is this a straight line in space-time or just space?

    Just space. You've been given a geometric description - r is geometric distance.
