    Determining the magnitude of the magnetic field acting on a particle

    1. *Is my solution correct? Homework Statement A positively charged particle of mass 7.2 X 10^-8 kg is traveling due east with a speed of 85 m/s and enters a 0.31T uniform magnetic field. The particle moves through one-quarter of a circle in 2.2 X 10^3 seconds, at which time it leaves the...

    Determining the radius of curvature mass spectrometre question

    Homework Statement A mass spectrometer is an important tool in the study of air pollution. However, one of the difficulties faced by scientists is that carbon monoxide molecules (CO), which are major contributors to air pollution, have very nearly the same mass as harmless nitrogen molecules...

    Undergrad Proof that the area under the curve dh/dt against t = height

    Hi, I have conducted an experiment to calculate the rate of change of water as it passes through 1cm levels (10 down to 0) across a uniform cross section of a juice bottle (rectangular prism shaped). I was wondering how I could verify/prove that the area under the curve is equal to the initial...

    Undergrad Homopolar Motor Limiting factor angular velocity

    I am doing an experiment involving determing the angular velocity of a homopolar motor (simple set up of the screw, battery, magnet and copper wire) and was wondering what the limiting factor on the speed would be. One website suggests that this might be back emf.
