Aproton and an electron have the same kinetic energy upon entering a region of constant magnetic field. what is the ratio of the radii of their circular paths?

v 154.9= 0.9 length length s little over 154.9cm

  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.
