Answer :

cos-1 (3/4)

Given mass = m


Let angular amplitude be


Velocity be V


Tension in the string is maximum at mean position



Tension is minimum at extreme position



Given,


= 2





From the law of conservation energy


[loss in P.E is equal to gain in K.E]



Substituting in the above equation




2



=
