Kinematics Question 299
Question: Two adjacent sides of a parallelogram are represented by the two vectors $ \hat{i}+2\hat{j}+3\hat{k} $ and $ 3\hat{i}-2\hat{j}+\hat{k} $ . What is the area of parallelogram [AMU 1997]
Options:
A) $ 10\sqrt{2} $
B) $ 20 $
C) $ 2\sqrt{10} $
D) 10
Correct Answer: A $ Mass=\frac{Force}{Acceleration}=\frac{|\vec{F}|}{a} $ = $ \frac{\sqrt{36+64+100}}{1} $ $ =10\sqrt{2}\ kg $
