A) \[\frac{4b-a}{3}\]
B) \[4b-3a\]
C) \[4a-3b\]
D) \[\frac{4a-b}{3}\]
Correct Answer: B
Solution :
Given, position vector of A and B is \[OA=a,\,\,OB=b,\,\,OC=?\] Also, given \[AC=4AB\] \[\Rightarrow \] \[OC-OA=4\,(OB-OA)\] \[\Rightarrow \] \[OC-a=4\,(b-a)\] \[\Rightarrow \] \[OC=4b-3a\]You need to login to perform this action.
