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