Kinematics Question 31
Question: Which pair of the following forces will never give resultant force of 2 N [HP PMT 1999]
Options:
A) 2 N and 2 N
B) 1 N and 1 N
C) 1 N and 3 N
D) 1 N and 4 N
Show Answer
Answer:
Correct Answer: D
Solution:
If two vectors A and B are given then Range of their resultant can be written as $ (A-B)\le R\le (A+B) $ .
i.e. $ {R _{\max }}=A+B $ and $ {R _{\min }}=A-B $
If B = 1 and A = 4 then their resultant will lies in between 3N and 5N. It can never be 2N
