A vector A has a magnitude of 140m and points in a direction of 48 degrees below the positive x-Axis. A second Vector B has a magnitude of 50m and points in the positive x direction. A) Draw a sketch showing how to add vectors A and B graphically. label your answer as Vector R.

B) what are the x and y components of these two vectors?
( you should be reporting 4 numbers here: 2 for A and 2 for B

C) find the x and y components of the resultant R.

D) what are the magnitude and direction of R?

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).
