A pendulum swings backwards and forwards passing through Y, middle point of the oscillation.
The first time the pendulum passes through Y, a stopwatch is started.
The twenty-first time the pendulum pass through Y, the stopwatch is stopped. The reading is T.
What is the time period of the pendulum?
A T/40
B T/21
C T/20
D T/10
The answer should be T/21 or T/20. How come T/10?

it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10

Here, in this example, the pendulum passes through y 21 times. So, it will do 10 complete oscillations and 1 half which is basically touching y. Therefore, the time period of the pendulum is T/10.

throughout the time period or the 21 swings the pendulum will pass through the point Y 21 times. so the answer is B(t/21)

It should be T/21 only as T is the total time and no of times it passes Y is 21.Therefore the answer is T/21

Yes it should be t/10 as the pendulum will pass through point y twice in its one revolution...... so the the time period should be t/10
