QUESTION:
The two charges \(q_1 \) and \(q_2 \) shown in Fig. E21.44 have equal magnitudes. What is the direction of the net electric field due to these two charges at points A (midway between the charges), B, and C if (a) both charges are negative, (b) both charges are positive, (c) \(q_1 \) is positive and \(q_2 \) is negative.
ANSWER:
Step 1 of 3
(a) Both charges are negative:
Electric field lines move from a positive charge to negative charge, hence, at B and C the electric field lines approaches the points and points to point A.
The electric field is zero at point A.
