    Electric Field On A Point Charge Due To A Uniformly Charged Rod

    Thank you for your quick responses! :) Tiny-tim: All of the examples in my physics book did in fact consist of charges that were perpendicular to the rod. I hadn't tried a problem where the charge was on the same axis as the rod so I thought I would give it a shot and make sure I could reason...

    Electric Field On A Point Charge Due To A Uniformly Charged Rod

    Homework Statement This is regarding setting up an integral to calculate the electric field on a point charge that is at a distance "a" from a uniformly charged rod of length "L". I have attached a picture of my work, which includes a diagram of the problem, and wanted to know if my thought...

    Circular Motion Dynamics. Car traveling in vertical circle

    That's what I was thinking as well. There have been several "loop the loop" problems that are similar to this one where roller coasters are moving at constant velocities around circular tracks, and I've been able to find accelerations by using (V^2)/R. NOTE: I just realized something. The...

    Circular Motion Dynamics. Car traveling in vertical circle

    Homework Statement A small car with mass .800 kg travels at a constant speed of 12m/s on the inside of a track that is a vertical circle with radius 5.0m. If the normal force exerted by the track on the car when it is at the top of the track is 6.00N, what is the normal force at the bottom of...

    1-D Kinematics Problem/Free Fall. A helicopter carrying Dr. Evil

    1-D Kinematics Problem/Free Fall. "A helicopter carrying Dr. Evil..." NOTE: I'm new here and I wanted to make sure I am not breaking the rules: I show most of my work step by step for this problem since there are so many things going on in it. My question is whether or not my though process is...
