Statement-I:

\vec{a}=\hat{i}+p \hat{j}+2 \hat{k}

and

\vec{b}=2 \hat{i}+3 \hat{j}+q \hat{k}

are parallel vectors if

p=\frac{3}{2}, q=4

.
Statement-II: If

\vec{a}=a_1 \hat{i}+a_2 \hat{j}+a_3 \hat{k}

and

\vec{b}=b_1 \hat{i}+b_2 \hat{j}+b_3 \hat{k}

are parallel, then

\frac{a_1}{b_1}=\frac{a_2}{b_2}-\frac{a_3}{b_3}

View answer and explanation

Correct option: A

Statement-I is true and statement-II is true

Statement-I is true because the vectors are parallel when their components are proportional. Statement-II is true because it correctly states the condition for parallel vectors.
