  • question_answer The figure shows a block of mass m kept on inclined plane with inclination \[\theta .\] The tension in the string is:

    A)  8 N                            

    B)  10 N

    C)  0.8 N             

    D)  0

    Correct Answer: D

    Solution :

    We know \[\tan \alpha =0.8\] \[\alpha ={{\tan }^{-1}}(0.8)={{39}^{o}}\] The given angle of inclination is less than angle of repose. So, 1 kg block has no tendency to move. Therefore, T=0, Hence, the correction option is [d].
