The angular amplitude of a simple pendulum is 
. The maximum tension in its string will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The simple pendulum at angular amplitude 
is shown in figure.
Maximum tension in the string is
…(i)
When bob of the pendulum comes form 
to 
, it covers a vertical distance 
…(ii)
Also, during 
to 
, potential energy of bob converts into kinetic energy i.e., 
…(ii)
Thus, using Eqs. (i), (ii) and (iii), we obtain
