A) \[23{}^\circ \]
B) \[67{}^\circ \]
C) \[90{}^\circ \]
D) \[113{}^\circ \]
Correct Answer: B
Solution :
As\[{{5}^{2}}+{{12}^{2}}={{13}^{2}},\] so these forces will be acting along the sides of a right angled triangle. Angle between 5 N and 13 N \[=180-(90+23)\] \[=180-113={{67}^{o}}\]You need to login to perform this action.
