JEE Main & Advanced Physics NLM, Friction, Circular Motion Sample Paper Topic Test - Friction

  • question_answer
    With reference to the figure shown, if the coefficient of friction at the surfaces is 0.42, then the force F required to pull out the 6.0 kg block with an acceleration of 1.50 \[m\text{/}{{s}^{2}}\] will be:

    A) 36 N                            

    B) 24 N

    C) 84 N                            

    D) 51 N

    Correct Answer: D

    Solution :

    \[F-8\left( 0.42 \right)\left( 10 \right)-2\left( 0.42 \right)\left( 10 \right)=6\left( 1.5 \right)\]
