A batsman takes the first run by moving from \(A\) to \(B\) and then goes for the second run. When he reaches \(20~\text{yards}\) from \(B\) to \(D\) (see figure), he was run out. The net displacement of the batsman is:
| 1. | \(2\) yards | 2. | \(20\) yards |
| 3. | \(22\) yards | 4. | \(42\) yards |

Given below are two statements:
| Assertion (A): | The displacement of a body can be zero even when the distance travelled by it is not zero. |
| Reason (R): | Displacement is the longest distance between the initial and final positions of a body. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |

The initial and final positions of a man on the \(x\text-\)axis are given for the following three cases:
| (i) | \((-4~\text m, 6~\text m)\) |
| (ii) | \((4~\text m,-3~\text m)\) |
| (iii) | \((-4~\text m, 2~\text m)\) |
Which of these cases represent a negative displacement?
1. (i)
2. (ii)
3. (iii)
4. (i) and (iii)
