A 6 m wire carries a current of 7 A toward the +x direction. A magnetic force of 7.0x10-6N acts in the wire in the -y direction. Find the magnitude and direction of the magnetic field producing the force

hypothesising or postulating

  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.
