A) \[-2\hat{i}+6\hat{j}+4\hat{k}\]
B) \[-2\hat{i}+3\hat{j}+3\hat{k}\]
C) \[-2\hat{i}+3\hat{j}+5\hat{k}\]
D) \[2\hat{i}-3\hat{j}-5\hat{k}\]
Correct Answer: C
Solution :
Let\[A\equiv (0,3,-1)\]and \[B\equiv (-2,6,4)\] \[\overrightarrow{A}=3\hat{j}-\hat{k}\]and \[\overrightarrow{B}-2\hat{j}+6\hat{j}+4\hat{k}\] The displacement vector from A to B \[=\overrightarrow{B}-\overrightarrow{A}\] \[=(-2\hat{i}+6\hat{j}+4\hat{k})-(3\hat{j}-\hat{k})\] \[=-2\hat{i}+3\hat{j}+5\hat{k}\]You need to login to perform this action.
