Question

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?

Answer 1

Answer:

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;

$E = \frac{v}{\mu}$

where;

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

Substitute the given values and solve for E

$E = \frac{v}{\mu}\\\\E = \frac{3*10^{-7}}{8.1*10^{-8}}\\\\ E = 3.704 \ N/C$

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