  • question_answer
    A Physics teacher of class 12th was explaining the topic electric field lines. She then told the class that, at some locations, electric field due to two identical negative charges can be zero. Explain the reason behind this with a situation. Also, write the value shown by Physics teacher.


    Consider the situation, when the electric fields created by the two charges are equal in magnitude and opposite in direction at some location. Then, at the midway point in between and along line joining two charges of the same type and magnitude, the electric field would be zero. The teacher has good knowledge of the subject and a good instructor.
