A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.40km/s in the + x-direction experiences a force of 2.06 times 10-16N in the + y -direction, and an electron moving at 4.70km/s in the -z-direction experiences a force of 8.60 times 10-16N in the + y-direction. Part A What is the magnitude of the magnetic field? Part B What is the direction of the magnetic field? (in the xz-plane) Part C What is the magnitude of the magnetic force on an electron moving in the - y-direction at 3.70km/s ? Part D What is the direction of this the magnetic force? (in the xz-plane)

0.19 m/s and 0.45 m/s

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
