3-1.Vectors
medium
Two vectors $A$ and $B$ have equal magnitude $x$. Angle between them is $60^{\circ}$. Then, match the following two columns.
| colum $I$ | colum $II$ |
| $(A)$ $|A+B|$ | $(p)$ $\frac{\sqrt{3}}{2} x$ |
| $(B)$ $|A-B|$ | $(q)$ $x$ |
| $(C)$ $A \cdot B$ | $(r)$ $\sqrt{3} x$ |
| $(D)$ $|A \times B|$ | $(s)$ None |
A$( A \rightarrow r , B \rightarrow q , C \rightarrow s , D \rightarrow p )$
B$( A \rightarrow q , B \rightarrow r , C \rightarrow s , D \rightarrow p )$
C$( A \rightarrow s , B \rightarrow q , C \rightarrow r , D \rightarrow p )$
D$( A \rightarrow r , B \rightarrow q , C \rightarrow p , D \rightarrow s )$
