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:

The strength of the electric force is related to the density of electric field lines. The denser the electric field lines, the stronger the electric field, and thus the greater the electric force (since \(F = qE\), where \(F\) is the electric force, \(q\) is the charge of the test charge, and \(E\) is the electric - field strength). Position 4 has the densest electric field lines among the four positions.

Answer:

4
