Question

Find the electric field at the origin, point O. Give the x and y components of the electric field as an ordere?

PART 1:

Two point charges are placed on the x axis. (Intro 1 figure) The first charge, = 8.00 , is placed a distance 16.0 from the origin along the positive x axis; the second charge, = 6.00 , is placed a distance 9.00 from the origin along the negative x axis.

PART 2:

Now, assume that charge q2 is negative; q2 = -6nC. (Part B figure) What is the net electric field at the origin, point O?

Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures. Keep in mind that an x component that points to the right is positive and a y component that points upward is positive.

Answer 1

This is the best answer for Find the electric field at the origin, point O. Give the x and y components of the electric field as an ordere?

Let a positive field be to the right so q1 will generate a + field and q2 a negative field

So E = k*(q1/r1^2 - q2/r2^2) = 9.0x10^9*(6.0x10^-9/9^2 - 8x10^-9/16^2) = 0.385 N/C

Part 2 Now both field point to the left so

E = k*(-q1/r1^2 - q2/r2^2) = 9.0x10^9*(-6.0x10^-9/9^2 - 8x10^-9/16^2) = -0.948 N/C

Answer 2

How could i'm getting ? if the two rather one in all my expenditures are 4 micro C placed at x= 1m and x =-1m and that i could prefer to calc the value E of the internet electric powered field at y= 0.6m? idk what to anticipate x and y to plug into arctan?, the only way i think of like i visit do it finally finally end up being 0 by employing actuality it may properly be arctan(0/0.6)
