9. A beam of electron is injected into electric fields of 103V/m
and a magnetic field of 10 gauss at right angle to each other
and also perpendicular to the direction of the motion of the
electrons. The beam remains undedicated. What is the
velocity of electron beam?

answer: (431,2)

step-by-step explanation:

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.
