Questions  

Two forces are acting on a rope lying on a smooth table as shown in figure.

Which of the following statement (s) is/are correct?
I. In moving from A to B, tension on string decreases from 2F to F.
II. Situation will becomes indeterminant, if we take it a massless string. 

a
Only I
b
Only II
c
Both I and II
d
None of these

detailed solution

Correct option is C

As forces at two ends of string are different, so tension on it decreases from 2F to F in moving from A to B.  In case of massless string,  a=2F-F0=∞Hence, both statements are correct.
