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 \[=\,\,\,mg\,\sin \,\,\theta \] \[=\,\,\,5\times 10\times sin30{}^\circ \] \[=\,\,\,5\times 10\times \frac{1}{2}\] \[=\,\,25\,N\]You need to login to perform this action.
