Q1:

If \(|\vec{A}|=2\) and \(|\vec{B}|=4\), then match the relations in Column I with the angle \(\theta\) between \(\vec{A}\) and \(\vec{B}\) in Column II.

	Column I		Column II
(a)	\(\vec{A}.\vec{B}=0\)	(i)	\(\theta=0^{\circ}\)
(b)	\(\vec{A}.\vec{B}=8\)	(ii)	\(\theta=90^{\circ}\)
(c)	\(\vec{A}.\vec{B}=4\)	(iii)	\(\theta=180^{\circ}\)
(d)	\(\vec{A}.\vec{B}=-8\)	(iv)	\(\theta=60^{\circ}\)

Choose the correct answer from the options given below:

1.	(a)–(iii), (b)-(ii), (c)-(i), (d)-(iv)
2.	(a)–(ii), (b)-(i), (c)-(iv), (d)-(iii)
3.	(a)–(ii), (b)-(iv), (c)-(iii), (d)-(i)
4.	(a)–(iii), (b)-(i), (c)-(ii), (d)-(iv)
