An electric field is applied to a solution containing bromide ions. As a result, the ions move through the solution with an average drift speed of 3.0 × 10−7 m/s. The mobility of bromide ions in solution is 8.1 × 10−8 (m/s)/(N/C). What is the magnitude of the net electric field inside the solution?

The magnitude of the net electric field inside the solution is 3.704 N/C

Explanation:

Given;

average drift speed, v = 3 x 10⁻⁷ m/s

mobility of the bromide ions, μ = 8.1 x 10⁻⁸ (m/s)(N/C)

The magnitude of the net electric field inside the solution is given by the equation below;

where;

E is the magnitude of the net electric field inside the solution

Substitute the given values and solve for E

Therefore, the magnitude of the net electric field inside the solution is 3.704 N/C

  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.
