Vectors Question 203
Question: If two vectors $ 2\hat{i},+3\hat{j},+,\hat{k} $ and $ -4\hat{i},-6\hat{j},-\lambda \hat{k} $ are parallel to each other, then value of $ \lambda $ is
Options:
A) 0
B) 2
C) 3
D) 4
Correct Answer: B [b] The coefficient of $ \hat{i},,\hat{j} $ and $ \hat{k} $ should bear a constant ratio. or $ \frac{2}{-4},=\frac{3}{-6},=\frac{1}{-\lambda } $ .
