5. Collect data: Select the DESCRIPTION tab. On the SIMULATION pane, turn on Show mass. This lists the total mass of the cart. Each fan exerts a force of 4.0 newtons (N). One newton is the force required to
accelerate a 1-kg object at a rate of 1 m/s?.
For each combination, record the total force, total mass, and acceleration. On the last column, multiply the
mass (m) and acceleration (a).

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). (e
