The force exerted by an electric charge at the origin on a charged particle at a point (x, y, z) with position vector r = x, y, z is f(r) = kr/|r|3 where k is a constant. (see this example.) find the work done as the particle moves along a straight line from (2, 0, 0) to (2, 3, 5).

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.
