    A stretching force of 1000 Newton is applied at one end of a spring balance and an equal stretching force is applied at the other end at the same time. The reading of the balance will be

    A)  2000 N

    B)  0 N

    C)  1000N  

    D)  500N

    Correct Answer: C

    Solution :

     One of the forces is necessary to maintain the overall system in equilibrium. The spring gets stretched due to the other force. So, reading of the balance will be due to one of the forces, though the net force on the spring is zero.
