Question

Part A

In the figure we see that the electric potential increases by 10.0 as one moves 4.00 in the positive direction. Use this information to calculate the x component of the electric field.

-I got -2.50E2 and this was correct

Part B

Apply the same reasoning as in part A to calculate the ycomponent of the electric field.

-I got -5.00E2 and this was correct

Part C

Combine the results from parts A and B to find the magnitude of the electric field for this system.

-Please help!

Part D

Combine the results from parts A and B to find the direction of the electric field for this system.

-Please help!

Explanation / Answer

c)

E = (Ex^2 + Ey^2) = (2.5e2*2.5e2+5e2*5e2) = 559

d)

= 180 + arctan(5e2/2.5e2) = 180 + 63.4 = 243 degrees
