NEET AIPMT SOLVED PAPER MAINS 2010

  • question_answer
    Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in between the gap of the two magnets at a distance D from the centre O as shown in the figure The force on the charge Q is                                      

    A)  zero

    B)  directed along OP

    C)  directed along PO

    D)  directed perpendicular to the plane of paper

    Correct Answer: A

    Solution :

    The force of attraction on Q by the North Pole of first magnet is F. The force of attraction on the same charge by n the North Pole of another magnet must be opposite to that of the first magnet. Thus, they concel the effect of one other and hence force on the charge Q is zero.
