Question

In the given diagram of a simple pendulum, the time taken by the bob to move from X to Z is 't1' and from Zto O is 't2'.The time period of this simple pendulum is -

Answer 1

I think the answer is 4(t1+ t2), as t(XOYOX) is time period. Pendulum requires same time to cover XO to OY and XZ + XO = XO

Answer 2

the time of the simple pendulum is 4(t1+t2)
