Two blocks of mass m 1 and m 2 interconnected with a spring of stiffness K are kept on a smooth horizontal surface. Which of the following ratios is/are correct, when the spring is extended and released?
A
B
C
D
Where X = displacement, v = speed, P = momentum, a = acceleration, all relative to the surface, KE = kinetic energy, F = force. 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, d)
(F ext ) system = 0 ⇒ ⇒ 
= 0 ⇒ ⇒ p 1 = p 2 .
⇒ ⇒ m 1 
+ m 2 
= 0 ⇒ ⇒ 
(since p 1 = p 2 )
Where x = deformation of the spring ⇒ ⇒ 
= 1 ⇒ ⇒ 
= 1
⇒ ⇒ 
. Hence, the correct choice is
