Chapter 26: Q. 1 (page 737)

What is the potential difference between xi=10cm and xf=30cm in the uniform electric field Ex=1000V/m?

Short Answer

Expert verified

-200voltsis the potential difference.

Step by step solution

01

Given information and formula used

Given :

xi=10cm ; xf=30cm

Uniform electric field : Ex=1000V/m

Theory used :

The potential decrease is provided by the formula : ∆V=-E(xf-xi)

02

Calculating the required the potential difference 

The field is uniform and oriented in the xdirection.

So, using the formula we get :

role="math" localid="1649493329471" ∆V=-E(xf-xi)⇒∆V=-200V

A nerve cell in its resting state has a membrane potential of -70mV, meaning that the potential inside the cell is 70mV less than the potential outside due to a layer of negative charge on the inner surface of the cell wall and a layer of positive charge on the outer surface. This effectively makes the cell wall a charged capacitor. When the nerve cell fires, sodium ions,Na+, flood through the cell wall to briefly switch the membrane potential to +40mV. Model the central body of a nerve cell-the soma-as a 50μmdiameter sphere with a 7.0-nm-thick cell wall whose dielectric constant is 9.0. Because a cell's diameter is much larger than the wall thickness, it is reasonable to ignore the curvature of the cell and think of it as a parallel-plate capacitor. How many sodium ions enter the cell as it fires?

In Problems 75 through 77, you are given the equation(s) used to solve a problem. For each of these, you are to: a. Write a realistic problem for which this is the correct equation (s). b. Finish the solution to the problem.
