A) 10 N, 15 N
B) 20 N, 30 N
C) 2 N, 3 N
D) 5 N, 6 N
Correct Answer: B
Solution :
\[Frictional\, force,\, =f\,\,=\, 28.2\, cos 45{}^\circ \] \[=\,\,28.2\,\,\times \frac{1}{\sqrt{2}}\,\,=\,\,20\,\,N\] Normal reaction \[\operatorname{R} = 50 -28.2 \,sin\, 45{}^\circ \,=\, 30 N\]You need to login to perform this action.
