JEE Main & Advanced Physics Magnetic Effects of Current / करंट का चुंबकीय प्रभाव Question Bank Force and Torque on a Current Carrying Conductor

  • question_answer
    There long straight wires A, B and C are carrying current as shown figure. Then the resultant force on B is directed ..... [KCET 2004]

    A)            Towards A

    B)            Towards C

    C)            Perpendicular to the plane of paper and outward

    D)            Perpendicular to the plane of paper and inward

    Correct Answer: B

    Solution :

               \[F\propto {{i}_{1}}{{i}_{2}}\], so force on B due to C will be greater than that due A. Hence net force on B acts towards C.
