    A body of mass 5 kg is suspended by a spring balance on an inclined plane as shown in figure.              The spring balance will measure

    A)  50 N                           

    B)  25 N

    C)  500 N              

    D)  10 N

    Correct Answer: B

    Solution :

    Acceleration of the body down the rough inclined plane \[=\,\,g\,\,sin \theta \] \[\therefore \] Force applied on spring balance \[=\,\,\,mg\,\sin \,\,\theta \] \[=\,\,\,5\times 10\times sin30{}^\circ \] \[=\,\,\,5\times 10\times \frac{1}{2}\] \[=\,\,25\,N\]
