Vectors Question 200
Question: What is correct?
Options:
A) $ |\vec{a}-\vec{b}|, \leq |\vec{a}|-|\vec{b}| $
B) $ |\vec{a}-\vec{b}|,\le |\vec{a}|+|\vec{b}| $
C) $ |\vec{a}-\vec{b}|,\ge |\vec{a}|-|\vec{b}| $
D) $ |\vec{a}-\vec{b}|,>,||\vec{a}|-|\vec{b}|| $
Correct Answer: D $ \vec{a}-,\vec{b} $ is nothing but addition of $ \vec{a} $ and $ -\vec{b} $ . So, the magnitude of $ \vec{a}-\vec{b} $ will lie between $ |\vec{a}|-,|\vec{b}| $ and $ |\vec{a}|+,|\vec{b}| $ .
