Q. No.It is found that \(|\vec{A}+\vec{B}|=|\vec{A}|\). This necessarily implies:
| 1. | \(\vec{B}=0\) |
| 2. | \(\vec{A},\) \(\vec{B}\) are antiparallel |
| 3. | \(\vec{A}\) and \(\vec{B}\) are perpendicular |
| 4. | \(\vec{A}.\vec{B}\leq0\) |

Given below in Column-I are the relations between vectors \(a,\) \(b,\) and \(c\) and in Column-II are the orientations of \(a,\) \(b,\) and \(c\) in the XY-plane. Match the relation in Column-I to the correct orientations in Column-II.
| Column-I | Column-II | ||
| a | \(a + b = c\) | (i) |  |
| b | \(a- c = b\) | (ii) |  |
| c | \(b - a = c\) | (iii) |  |
| d | \(a + b + c = 0\) | (iv) |  |
| 1. | a(ii), b (iv), c(iii), d(i) |
| 2. | a(i), b (iii), c(iv), d(ii) |
| 3. | a(iv), b (iii), c(i), d(ii) |
| 4. | a(iii), b (iv), c(i), d(ii) |

For two vectors \(\vec A\) and \(\vec B\), |\(\vec A\)+\(\vec B\)|=|\(\vec A\) - \(\vec B\)| is always true when:
| (a) | |\(\vec A\)| = |\(\vec B\)| ≠ \(0\) |
| (b) | \(\vec A\perp\vec B\) |
| (c) | |\(\vec A\)| = |\(\vec B\)| ≠ \(0\) and \(\vec A\) and \(\vec B\) are parallel or antiparallel. |
| (d) | when either |\(\vec A\)| or |\(\vec B\)| is zero. |
Choose the correct option:
1. (a), (d)
2. (b), (c)
3. (b), (d)
4. (a), (b)
