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

  • question_answer
    A block of mass 1 kg lies on a horizontal surface in a truck. The coefficient of friction between the block and the surface is 0.4. if the acceleration of the truck is 5 \[m\text{/}{{s}^{2}}\] Find the frictional force acting on the block?

    A) 2 N                              

    B) 55 M               

    C) 4 N     

    D) 10 N

    Correct Answer: C

    Solution :

              Limiting friction \[\mu \,N=\mu mg=4\,N\]
