Kinematics Question 23
Question: Maximum and minimum magnitudes of the resultant of two vectors of magnitudes P and Q are in the ratio $ 3:1. $ Which of the following relations is true
Options:
A) $ P=2Q $
B) $ P=Q $
C) $ PQ=1 $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
According to problem $ P+Q=3\ \text{and }P-Q=1 $ By solving we get $ P=2\ \text{and }Q=1 $
$ \frac{P}{Q}=2 $ therefore $ P=2Q $
