A) \[\frac{12}{5}\mathbf{a}+\frac{13}{5}\mathbf{b}\]
B) \[\frac{12}{5}\mathbf{a}-\frac{13}{5}\mathbf{b}\]
C) \[\frac{3}{5}\mathbf{a}-\frac{2}{5}\mathbf{b}\]
D) None of these
Correct Answer: B
Solution :
Position vectors of the points which divides internally is, \[\frac{3(2\mathbf{a}-3\mathbf{b})+2(3\mathbf{a}-2\mathbf{b})}{5}=\frac{12\mathbf{a}-13\mathbf{b}}{5}.\]You need to login to perform this action.
