Question

the image shows the electric field lines around two charged particles. at which position would the electric force be greatest? 1 2 3 4

Explanation:

Step1: Recall electric - field concept

The electric force on a charged particle is related to the electric - field strength. The electric - field strength is proportional to the density of electric - field lines.

Step2: Analyze the density of field lines

We need to check the density of the electric - field lines at each position. The more closely packed the electric - field lines are, the stronger the electric field, and the greater the electric force on a charged particle placed at that position.

Step3: Compare positions

Position 4 has the most closely packed electric - field lines compared to positions 1, 2, and 3.

Answer:

4
