2. the figure shows three electric charges labeled $q_1, q_2, q_3$, and some electric - field lines in the region surrounding the charges. what are the signs of the three charges? a) $q_1$ is positive, $q_2$ is negative, $q_3$ is positive b) $q_1$ is negative, $q_2$ is positive, $q_3$ is negative c) $q_1$ is positive, $q_2$ is positive, $q_3$ is negative d) all three charges are negative e) all three charges are positive

2. the figure shows three electric charges labeled $q_1, q_2, q_3$, and some electric - field lines in the region surrounding the charges. what are the signs of the three charges? a) $q_1$ is positive, $q_2$ is negative, $q_3$ is positive b) $q_1$ is negative, $q_2$ is positive, $q_3$ is negative c) $q_1$ is positive, $q_2$ is positive, $q_3$ is negative d) all three charges are negative e) all three charges are positive

Answer

Explanation:

Step1: Recall electric - field line properties

Electric field lines start from positive charges and end on negative charges.

Step2: Analyze the field - line directions

For (Q_1), the electric - field lines are starting from it, so (Q_1) is positive. For (Q_2), the electric - field lines are ending on it, so (Q_2) is negative. For (Q_3), the electric - field lines are starting from it, so (Q_3) is positive.

Answer:

A. (Q_1) is positive, (Q_2) is negative, (Q_3) is positive
