An electron moving in the positive y direction at right angles to a magnetic field, experiences a magnetic force in the negative x direction.

An electron moving in the positive y direction at right angles to a magnetic field, experiences a magnetic force in the negative x direction. what is the direction of the magnetic field?

a) it is in the negative z direction

b) it is in the postive y direction

c)it is in the positive z direction

d) it is in the negative x direction

e) it is in the postive x direction

Expert Solution

electron moves in positive y direction

magnetic feild is perpendicular to the electron

magnetic force in the negative x direction

using right hand rule

magnetic force is given as

Force =q * V X B

now, v = v * j

Force = - F i

as the charge on the electron is negative ,

the field is out of the page , c)it is in the positive z direction

Consider an electron initially moving in the positive x-direction along the negative x-axis with an energy E. At the origin the electron encounters a square barrier; the potential energy U (x) changes abruptly, from ? U(x)=0? for x<0, to U ( x) 1.0eV for 0<x<a. to U(x)=0 for x>a, where the barrier width a=1 nm . Graph the transmittance as a function of energy, for the range 0 <E<5eV . For what values of energy is there a transmission resonance?

An electron is moving north; what direction should a magnetic field be oriented, so the magnetic force on the electron just balances the gravitational force? A square loop is in the x-y plane, with its top and bottom parallel with the x-axis, and its sides parallel with the y-axis. It carries a clockwise current when viewed from the positive z-axis. There is a constant magnetic field pointed in the x-axis direction. What are then directions of the magnetic forces on the four...
