Options:
A) $ 2\mathbf{a}+\mathbf{b}+\mathbf{c} $
B) $ \mathbf{a}+2\mathbf{b}+\mathbf{c} $
C) $ \mathbf{a}+\mathbf{b}+2\mathbf{c} $
D) $ \mathbf{a}+\mathbf{b}+\mathbf{c} $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ \mathbf{v}=\mathbf{b}+\mathbf{c} $ ?..(i) $ \mathbf{w}=\mathbf{b}+\mathbf{a} $ ?..(ii) We have, $ \mathbf{x}=\mathbf{v}+\mathbf{w}=\mathbf{a}+2\mathbf{b}+\mathbf{c} $ .
