A Smooth ring of Mass 'M' is threaded on a string as shown in the figure. Various portions of strings are vertical. What is the condition if the ring alone is to remain at rest –
A
= 
+ 
B
= 
+ 
C
= 
+ 
D
= 
+ 
Text Solution
Verified by ExpertsThe correct answer is:
A
Since 'M' is at rest the tension in the string = 
Let acceleration of m and m' is 'f' one will move downward and other will move upward
mg – 
= mf ……. (i)
– m'g = m'f ……. (ii)
Solving equation (i) and (ii)
= 
+
