Two identical balls are interconnected with massless and inextensible thread. The system is in gravity free space with the thread just taut. Each ball is imparted a velocity v, one towards the other ball and the other perpendicular to the first at t = 0, then -
A
The thread will become taut at t = 
B
The thread will become taut at some time t < 
C
The thread will always remain taut for t > 
D
The kinetic energy of the system will always remain mv 2
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, c)
Now,
Total K.E. = 
+ 
mv 2 
= 
mv 2
