the image shows the electric field lines around two charged particles. at which position would the electric force be greatest? 1 2 3 4
Answer
Explanation:
Step1: Recall electric - field and force relation
The electric force on a charge $F = qE$, where $q$ is the charge and $E$ is the electric - field strength. The electric - field strength is proportional to the density of electric - field lines.
Step2: Analyze line density at each position
Position 4 has the highest density of electric - field lines among positions 1, 2, 3, and 4. So the electric field $E$ is greatest at position 4. Since $F = qE$ and assuming a constant test charge $q$, the electric force $F$ is greatest at the position with the greatest electric - field strength.
Answer:
4
