    Free Charge Moving in Uniform Magnetic Field

    As far as I understood from his instructions, he wants to know in which direction can we flick the charge so that it will reach the target at (-c,-c). I don't believe he wants a complete list of possible quadrant directions - only whether the charge should be sent off in +x, -x, +y, or -y...

    Free Charge Moving in Uniform Magnetic Field

    Thank you so much! I think I've got it now: The path of the charged particle will be shaped by the Lorentz Force F=qVB, which will act perpendicular to the particle's velocity. Geometrically speaking, the particle will move in a uniform counterclockwise circular motion perpendicular to the...

    Free Charge Moving in Uniform Magnetic Field

    Homework Statement The drawing shows a particle carrying a positive charge +q at the origin (of x and y axis), as well as a target location located in the lower left quadrant. The target is just as far from the x-axis as it is from the y axis. There is also a uniform magnetic field...

    Electrical repuls./attract. btwn uniform charge density and object

    Thank you! I see the mistake I've made: q=mg/E =(100)(9.8)/(1.13x10^5) =8.67x10^-3 C Would the gravitational acceleration be negative, since it is balancing the Electric Force, which is pointing upward? In order for the "hoversuit" to accelerate upward, the strength of the...

    Electrical repuls./attract. btwn uniform charge density and object

    Thank you so much! Finally, I have an idea on how to approach this. So, if the "large flat sheet" is infinite in extent, could I find electric field by using Gauss's Law, E=2∏kσ? And since the charge of the sheet is positive, the field would be directed radially out out from the line...

    Electrical repuls./attract. btwn uniform charge density and object

    Homework Statement Imagine that you've been invited to try out a new "hoversuit," and here's how it works: Someone has set up a large flat sheet, many kilometers across, somewhere on the Earth, and they've charged the sheet up to a uniform charge density σ = +2 x 10^-6 C/m^2. You are...
