A) Zero
B) Along west
C) Along east
D) Vertically downward
Correct Answer: B
Solution :
Direction of vector A is along z-axis \\[\vec{A}=a\hat{k}\] Direction of vector B is towards north \ \[\vec{B}=b\hat{j}\] Now \[\vec{A}\times \vec{B}=a\hat{k}\times b\hat{j}=ab(-\hat{j})\] \ The direction is \[\vec{A}\times \vec{B}\] is along west.You need to login to perform this action.
