  • question_answer
    Figure shows electric field lines in which an electric dipole                                                                                      is placed at shown. Which of the following statements is correct?                                                                                                             (NCERT EXEMPLAR)

    A) The dipole will not experience any force

    B) The dipole will experience a force towards right

    C) The dipole will experience a force towards left

    D) The dipole will experience a force upwards

    Correct Answer: C

    Solution :

    (c) The dipole will experience a force towards left The spacing between electric lines of force increases from left to right. Therefore, E on left is greater than E on right. Force on +q charge of dipole is smaller and to the right. Force on -q charge of dipole is bigger and to the left. Hence, the dipole will experience a force towards the left.
