Work Energy And Power Question 55
Question: Two bodies A and B having masses in the ratio of 3 : 1 possess the same kinetic energy. The ratio of their linear momenta is then [Haryana CEE 1996]
Options:
A) 3 : 1
B) 9 : 1
C) 1 : 1
D) $ \sqrt{3}:1 $
Show Answer
Answer:
Correct Answer: D
Solution:
$ P=\sqrt{2mE} $ $ \frac{P_1}{P_2}=\sqrt{\frac{m_1}{m_2}} $
(if E = constant) $ \frac{P_1}{P_2}=\sqrt{\frac{3}{1}} $
