As the angular displacement of pendulum increases the tension in string decreases.
Tension in the string is basically the component of its weight which supports it
restoring force = - mg sin (theta)
tension balancing weight = mg cos (theta)
T = mg cos (theta)
T = Tmin when (theta) is maximum
or when displacement = amplitude
given Tmax = 2 Tmin
mg cos(0) = 2 mg cos (theta)
cos (theta) = 1/2
theta = angular amplitude = 60 degree
= pi/3 radians
