Question

Pre-Lab Exercises Exercise 1 Suppose there is a uniform electric field pointing in the positive a-direction with a magnitude of 5.0 V/m. The electric potential is measured to be 50 V at the position x = 10 m, what is the electric potential at other positions? Position [m] -200.00|10 1199 Electric Potential VI Exercise 2 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 zi = 0.25 cm and an electric potential value Vi-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-component pointing? Between the locations measured, where does the electric field z-component have the calculated value?

Please answer both exercises and show work.

Answer 1

1. Because electric field is constant so potential is proportional to distance.

Because electric field is constant so potential is proportional to distance. potential = field times position 50 = 5 times 10 E = -dv/dr E_avg = -Delta v/ Delta r = -(15 - 36)/(0.55 - 0.25) times 10^-2 E_avg = 7000 N/C Direction is from Z_1 towards Z_Z, Between the loctions 7000 N/C Electric field is at position according to the change in Electric field . It depends on pattern of field charge
