A small car with mass 0.800 kg travels at constant speed on the inside of the track that is a vertical circle with radius 5.00 m. If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N. What is the normal force on the car when it is at the bottom of the track what is the speed of the car

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).
