Consider the following diagram in which an inextensible string connects two blocks passing via ring. The first block moves with a velocity of 2ms -1 and the second one moves with a velocity of 2 ms -1 . If the ring slides on horizontal rod then the value of v is (in m s -1 )
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The length of the string will remain constant. Hence,
2 cos 30 ° - 1 cos 30 ° = v cos 45 ° - 1 cos 45 °
