Two ring of mass m and 2 m are connected with a mass less spring and can slips over two frictionless parallel horizontal rails as shown in figure. Ring of mass m is given velocity 'v 0 ' in the direction shown. Maximum stretch in spring will be -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Maximum expansion in spring is given by
= 
[µ = Reduced mass]
x max = 
. v 0
= 
v 0
