A) \[\theta ={{\tan }^{-1}}\,\left( \frac{3}{4} \right)\] with the vertical towards South
B) \[\theta ={{\tan }^{-1}}\,\left( \frac{3}{4} \right)\] with the vertical towards North
C) \[\theta ={{\cot }^{-1}}\,\left( \frac{3}{4} \right)\] with the vertical towards South
D) \[\theta ={{\cot }^{-1}}\,\left( \frac{3}{4} \right)\] with the vertical towards North
Correct Answer: A
Solution :
Resultant velocity of rain \[v={{v}_{r}}+{{v}_{w}}=3i+4j\] \[\therefore \] \[\theta ={{\tan }^{-1}}\left( \frac{3}{4} \right)\] As wind is blowing from south, umbrella should be hold towards south.You need to login to perform this action.
