Question

how many times does the bob of an oscillating simple pendulum pass the mean position after 5 complete oscillations

Answer 1

When bob of pendulum reaches it's intial position it's considered as one oscillation or one cycle.

So it's obvious that in one oscillation bob passes mean position 2 times.

Hence, For 5 oscillations bob passes mean position (5×2 ) times. i.e 10 times.

Answer 2

One complete oscillation means when the Bob come to the starting position

So from the mean position it passes twice in one oscillation

So total no. is 5*2=10

which is required answer
