A heavy small-sized sphere is suspended by a string of length l. The sphere rotates uniformly in a horizontal circle with the string making an angle 
with the vertical. Then, the time period of this conical pendulum is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Radius of circular path in the horizontal plane
Resolving T along the vertical and horizontal directions, we get
… (i)
… (ii)
On dividing Eq. (ii) by Eq. (i),
we get
