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

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) \((-4~\text m, 2~\text m)\)
