Calculate the direction of the electric field (21.34)

In summary, the conversation is about calculating the direction of the electric field given four charges at the corners of a square. One charge is -39 and the others are -27.7. The individual has already found the correct answer but is unsure about the wording in one of the options and clarifies that it is most likely a typo for "through". They also confirm that the question is about the electric field, not the magnetic field.

The Attempt at a Solution


I already got the right answer, but I don't understand the wording of the second option. What does "diagonal passed throw" mean? Thank you all very much.

It's most likely a typo for "through". Passing through a point makes more sense.

And is this question about Electric or Magnetic field? The title and your post seem to mismatch...

Yes it should be electric field. Ah it's "through" not "throw" That makes more sense. Thank you again

FAQ: Calculate the direction of the electric field (21.34)

How do you calculate the direction of the electric field?

To calculate the direction of the electric field, you need to first determine the direction of the force acting on a positive test charge placed in the field. The direction of the electric field is then defined as the direction in which a positive test charge would move when placed in the field.

What is the formula for calculating the direction of the electric field?

The formula for calculating the direction of the electric field is E = F/q, where E is the electric field, F is the force acting on the test charge, and q is the magnitude of the test charge. This formula is also known as Coulomb's law.

How do you determine the direction of the force acting on a test charge in an electric field?

To determine the direction of the force, you need to consider the signs of the charges involved. Like charges repel each other and opposite charges attract each other. Therefore, the direction of the force will depend on the polarity of the charges in the electric field.

Can the direction of the electric field change?

Yes, the direction of the electric field can change depending on the location and configuration of the charges in the field. It is important to note that the direction of the electric field is always in the direction of the force acting on a positive test charge in the field.

How does the distance between charges affect the direction of the electric field?

The distance between charges does not affect the direction of the electric field. However, it does affect the strength of the electric field. As the distance between charges increases, the strength of the electric field decreases, but the direction remains the same.
