Arigid body is rotating counterclockwise about a fixed axis. each of the following pairs of quantities represents an initial angular position and a final angular position of the rigid body. which of the sets can occur only if the rigid body rotates through more than 180?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
