    Radius of Curvature of Ion in Magnetic Field

    Homework Statement A doubly ionized atom (charge = +2e) whose mass is 5.15E-26 kg is accelerated by a voltage of 3450 V and enters a region where a uniform magnetic field B = 0.100 T acts perpendicular to its motion. What is the radius of curvature of the path of the ion in the B-field...

    Engineering Solve Simple Circuit Problem: R1 = 2.00 Ω, R2 = 4.00 Ω, R3 = 8.00 Ω

    Here is the problem: The diagram below shows a circuit where; R1 = 2.00 Ω, R2 = 4.00 Ω, R3 = 8.00 Ω, V1 = 7.500 V, V2 = 10.00 V, and V3 = 8.00 V. (In solving the problems that follow, initially pick the current directions as shown. If the actual current turns out to be in the opposite...

    Charge Density of wire with potential difference

    Yes I think I found my problem, I can't use the simplified V = -Ed equation because E is not a uniform electric field in this case.

    Charge Density of wire with potential difference

    Problem: Consider a long charged straight wire that lies fixed and a particle of charge +2e and mass 6.70E-27 kg. When the particle is at a distance 1.91 cm from the wire it has a speed 2.80E+5 m/s, going away from the wire. When it is at a new distance of 4.01 cm, its speed is 3.20E+6 m/s...
