Laws Of Motion Question 327
Question: In the diagram shown, friction is completely absent. If a force F has been applied on the wedge such that it moves with a constant velocity than value of normal reaction N’ is
Options:
A) $ >F $
B) $ <F $
C) $ =F $
D) cannot find
Show Answer
Answer:
Correct Answer: A
Solution:
[a] For the wedge, $ N^{A}\sin \theta =F $
$ \therefore N^{A}=\frac{F}{\sin \theta }.\text{ As sin}\theta \text{1, and so N }!!’!!\text{ F} $
