Question

Trying to get prepared fro my lab tomorrow and I am having trouble with these two exercises. For part 1) I used V=qk/r but im not certain I did it correctly. Please help!

Exercise 1 Suppose there is a uniform electric field pointing in the positive -direction with a magnitude of 5.0 V/m. The Suppose there is a uniform electric field pointing in the positive a-direction with a magnitude of electric potential is measured to be 50 V at the position g 10 m. What is the electric potential at other positions? Position m] Electric Potential [V] 20 0.00 |10 ies 115o1gSLS 2a7 Exercise2 Suppose there is a non-uniform electric field and you measure the electric potential at two different locations along the z-axis. The first location has a position value = 0.25 cm and an electric potential value l' 36 V. The second location has a position value 22 = 0.55 cm and an electric potential value ½ = 15 V. Between the two locations, what is the average electric field z-component? Which direction is the average electric field z-componen pointing? Between the locations measured, where does the electric field z-compon everywhere, nowhere, only at the measured locations)? ent have the calculated value (e.g.

Explanation / Answer

Please see, Potential allways Decreases in the direction of Electric Field.

We know,
E = V/d

At x = 11 m,
5.0 = (50 - v)/(11 - 10)
V = 45 V

At x = 99 m,
5.0 = (50 - v)/(99 - 10)
V = -395 V

At x = 0 m,
5.0 = (50 - v)/(0 - 10)
V = 100 V

At x = -20 m,
5.0 = (50 - v)/(-20 - 10)
V = 200 V
