Assume that E = (1/2)mv^2 (meaning no relativistic effects)
v = (2E/m)^(1/2)
so then ...
The solution provides step-by-step calculations for solving the speed of an electron and a proton.
The drift velocity and Hall voltage.
The number density of free electrons in copper is 8.47 x 10 ^22 electrons per cubic centimeter. If a metal strip of copper 2 cm by 0.1 cm (thickness), magnetic field pointing up to top of paper, and a current og 10A, fins a) the drift velocity Vsubd and b) the Hall voltage (Assume the magnetic field is 2.0 T.)View Full Posting Details
