    If two masses (M & m) are connected on a horizontal plane and a force is applied on the combination, then the tension T depends on the

    A) force applied on the system

    B) whether force is applied on M or m

    C) both [a] and [b]

    D) Can't be predicted.

    Correct Answer: B

    Solution :

    [b] When force is applied on \[{{m}_{1}}\] Then \[T={{m}_{2}}a\]and when force is applied on\[{{m}_{2}}\], then\[T={{m}_{1}}a\]. Thus value of T is different for each case. And it depends on whether the force is applied on\[{{m}_{1}},\,or\,\,{{m}_{2}}.\]
