    Simplifying Lorentz Force Formula

    Hey everyone, I'm trying to make sure I did this question right. Any ideas would be greatly appreciated. Thanks! Homework Statement The general force that bends the electron in the e/m experiment is known as the Lorentz force, F = q(E + v x B), where force F, electric field E, velocity v...

    Minimize Effects of Earth's Magnetic Field

    Hey, So if I were doing an experiment in which I have a current carrying coil, at what angle to the Earth's magnetic field would I need to rotate the coil in order to minimize the effect of Earth's field? I was assuming parallel to the direction of the Earth's magnetic field. I assume it has to...

    Archived What angle maximizes the horizontal distance of a rocket launch?

    Hey everyone, I've been trying to do a problem in which I attempt to find the angle that maximizes the horizontal distance of a rocket, which has a stage with thrust and then a stage as a projectile. After a delay period, an ejection charge fires and causes the rocket to drop straight...

    Solving for Coordinate Angles in Statics Question

    Edit: Nevermind, it has been resolved. Homework Statement I have been attempting to solve what seems like a relatively pedestrian statics questions, but for some reason my answer is being marked as incorrect. The problem is as follows: Determine the magnitude and coordinate direction...
