# Question: Where does the electric field have the greatest magnitude?

Contents

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

## Where is the electric field strongest?

The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.

## Which electric field has the largest magnitude?

Therefore, Electric field at the dot has largest magnitude in case A. 2. Positive and negative charges come together and go away from the larger charge.

## Where is the electric field strongest between two point charges?

Electric fields around isolated charges – summary Look at the diagram below: close to the central charges, the field lines are close together. This is where the electric field is strongest. Further away from the central charges where the electric field is weaker, the field lines are more spread out from each other.

## What is the magnitude of the electric field at?

The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q. E has units of N/C. The magnitude of the electric field E created by a point charge Q is E=k|Q|r2 E = k | Q | r 2 , where r is the distance from Q.

## Why can’t electric field lines cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## Where is the electric field zero?

There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the “outside” of the smaller magnitude charge.

## What are the signs of q1 and q2?

Answer : Lines of force are moving outwards from q2, hence q2 is positively charged: +q2. Lines of force are going into q1, hence q1 is negatively charged : -q1. From the diagram, 18 lines of electric field come out of q2 and 6 lines of electric field get into q1.

## How do you know if an electric field is positive or negative?

The electric field is a vector field around a charged particle. … If the point charge is positive, field lines point away from it; if the charge is negative, field lines point toward it.

## Where is the electric field strongest in a dipole?

The pattern of the lines for the dipole indicates that the electric field is greatest in the region between and immediately surrounding the two charges, since the lines are closest together there.

## What is the electric field between two charges?

Electric field lines point away from positive charges (like charges repel) and towards negative charges (unlike charges attract). Field lines are drawn closer together where the field is stronger. Field lines do not touch or cross each other.
