    Hidden object at bottom of pool with a raft.

    Homework Statement A thief hides a diamond in the center of the bottom of a cylindrical pool of water of depth 3m and diameter 10m by placing a circular raft on the surface of the water. The center of the raft is directly above the diamond. What is the minimum radius of the raft that will...

    Electron moving in magnetic field. (Physics 2, non calc)

    The key to the problem was understanding that "horizontal" meant a uniform north field. Set up the magnetic field values along an xy plane and use SOHCAHTOA to find the angle. The north(horizontal) value is given, combined with the magnetic field calculated from part B and the problem is...

    Electron moving in magnetic field. (Physics 2, non calc)

    A. The path is circular. Can you offer more advice on part C. My diagram has electron heading east, with the force downwards and the magnetic field rotating in and out of the page, which makes it horizontal to the earth. While the electron is perpendicular to the Earth it with...

    Electron moving in magnetic field. (Physics 2, non calc)

    Homework Statement Electrons are fired Eastward at a certain location near Earth's surface. Ignore gravity. A. Describe the motion of the electrons and describe the trajectory they follow. B. If the electrons first return to their initial positions after 1.5 x 10^-6 seconds, determine the...

    Charged Particle Travelling Through Electric Field

    I would love some expert input. The particle holds a (-) charge, so the electric field force would move the particle upwards, but the gravitational force will push the particle down. Using the formula F = qE + m(-g) the Force = -.05N, the - indicating an overall Force in the downward...

    Charged Particle Travelling Through Electric Field

    The question states E in Newtons/meter. I emailed my professor but he has yet to get back to me. Edit: Was a typo on the homework. It is in N/C. I am not sure where to include gravity. Is the Force in the vertical direction (F = qE -mg) Since the electric field creates an upward force on...

    Charged Particle Travelling Through Electric Field

    Homework Statement A uniform electric field is non zero in a 20x10m region at the surface of the earth. Determine the direction and magnitude of the total vertical deflection of the incoming charged particle by the time it exits the region. The charged particle is traveling horizontal through...
