Question

Period of an oscillator is T. In what time it completes 3/8 th of its oscillation if motion begins from the fixed point. (a) 3/8 T (b) 5/8 T (c) 5/12 T (d) 8/3 T

Answer 1

Answer:

(a) 3/8 T

Explanation:

As given in the question,

time period of oscillator = T

We have to calculate the time taken by it to completes 3/8 th of its oscillation.

Since the motion is periodic so it will take its full-time period T to complete one oscillation along the mean position and it will take half of the time period for half oscillation along its mean position.

Similarly, if the body is only moving 3/8 th of its oscillation it will take 3/8 of its total time period T.

So, the answer will be 3/8 T.
