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
