if an answer for coulombs law is negative, it must mean the charges are opposite.\n(1 point)\ntrue\nfalse

Explanation:

Step1: Recall Coulomb's Law

Coulomb's Law is $F = k_e\frac{q_1q_2}{r^2}$, where $F$ is the electrostatic - force between two charges $q_1$ and $q_2$, $k_e$ is the electrostatic constant, and $r$ is the distance between the charges. The sign of $F$ depends on the product $q_1q_2$.

Step2: Analyze the sign of the force

If $q_1$ and $q_2$ have the same sign (both positive or both negative), then $q_1q_2>0$ and the force is positive, indicating a repulsive force. If $q_1$ and $q_2$ have opposite signs (one positive and one negative), then $q_1q_2 < 0$ and the force is negative, indicating an attractive force.
