# What are the strength and direction of the electric field at the position indicated by the dot in FIGURE EX23.4? Specify the direction as an angle above or below horizontal

The magnitude of the net electric field is . The direction of the electric field is .

See the step by step solution

## Step 1: Given information

Given a positive and a negative charge:

## Step 2: Explanation

The direction of the electric field due to the positive point charge is always acting away from the point charge and the electric field due to the negative charge acts towards the negative charge.

The electric field is a vector quantity. They cannot be added directly but can be added vectorially.

Calculate the electric field as follows:

Substitute
