Answer:

4.0s

Step-by-step explanation:

The period of the pendulum is the time taken for it to complete 1 full oscillation. This means that the pendulum moves this way for it to be 1 oscillation:

P ➟ Q ➟ R ➟ Q ➟ P

Since the pendulum only moved back to midpoint Q and not back to P, it has completed less than 1 oscillation.

Let each movement to the next section be 1 unit.

So 1 oscillation - 4units

In this case, the pendulum moved 3 units.

3 units ----- 3s

1 unit ----- 3÷3

1 unit ----- 1s

Thus 1 full oscillation would take 4(1)= 4s

Therefore, period of pendulum= 4s.
