Kinematics Question 316
Question: For a body moving with relativ it’stic speed, if the velocity is doubled, then [IIT JEE 2005]
Options:
A) it’s linear momentuM is doubled
B) it’s linear momentum will be less than double
C) it’s linear momentum will be more than double
D) it’s linear momentum remains unchanged
Show Answer
Answer:
Correct Answer: C
Solution:
Relativ it’stic momentum $ =\frac{m _{0}v}{\sqrt{1-v^{2}/c^{2}}} $ If velocity is doubled then the relativ it’stic mass also increases. Thus value of linear momentum will be more than double.
