A bob of mass ' m ' is connected to one end of string of length ' 
' & is free to rotate in vertical plane. The other end of string is connected with fixed support. Boob is given initial velocity shown in figure-
A
Bob will follow circular path only if 
B
If 
the tension in string at lowest position of bob will be 3 mg
the tension in string at lowest position of bob will be 3 mg C
If 
string will slack during subsequent motion
string will slack during subsequent motion D
If 
the tension in string will be impulsive at same position during subsequent motion
the tension in string will be impulsive at same position during subsequent motion
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, d): String will not slack if 
≥ ≥ mg cos θ ⇒ v ≥ ≥ 
. String will become slack if 
< mg cos θ & hence in subsequent motion tension will become impulsive at same position.
