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): Displacement of a body may be zero, when distance travelled by it is not zero.
Reason (R): The displacement is the longest distance between initial and final position.
 
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)
