Difference between torsion pendulum and simple pendulum?

Q. Statement I Three pendulums are suspended from ceiling as shown in Fig. These three pendulums are set to oscillate as shon by arrows, and it is found that all three have same time period. Noe, all three are taken to a place where acceleration due to gravity changes to 4/9th of its value at the first place. If spring pendulum makes 60 cycles in a given time at this place, then torsion pendulum and simple pendulum will also make 60 oscillation in same (given) time interval. Statement II: Time period of torsion pendulum is independent of acceleration due to gravity.

Torsional Pendulum

Ideal simple pendulum.

Define simple pendulum.

Two simple pendulums are drawn to same side from their mean position and are released simultaneously. Their time periods are 2 s and 3s. The phase difference between the pendulums when the longer pendulum completes one oscillation is

The period of simple pendulum

Find the phase difference between two simple pendulums of unequal lengths meeting at mean position while oscillating.

The motion of a simple pendulum is
