A) 2 cm, 7 cm
B) 1 cm, 4 cm
C) 2 cm, 3 cm
D) 2 cm, 4 cm
Correct Answer: A
Solution :
If two vectors A and B are given the range of their resultant can be written as \[(A-B)\le R\le (A+B)\]ie,\[{{R}_{\max }}=A+B\]and\[{{R}_{\min }}=A-B\]. If\[B=7\]and\[A=2,\]then their resultant will be in between 5 and 9. So, 3 cm cannot be the resultant of the pair.You need to login to perform this action.
