... The force exerted by the electric field on the charged particle points straight upward. So for part (a), the motion is perpendicular to the force, thus the work done is zero. For part (b), the force and motion are exactly in the same direction, so we have W = qEs = (28.0 × 10−9 C)(4.00 × 104 N/C)(0. ...

... When graphene is in the SSC the non-local resistance is very large, because that the spin current can dissipationlessly flow through the super-spin-fluid region. Here we emphasize that the changes of the normal resistance and non-local resistance are sharp, similar as the resistance change when a sa ...
