Statement-I: For an oscillating simple pendulum, the tension in the string is maximum at the mean position and minimum at the extreme position.
Statement-II: The velocity of oscillating bob in simple harmonic motion is maximum at the mean position.
Text Solution
Verified by ExpertsA
For an oscillating simple pendulum,
Let, tension in the string be
And let
be the angle made by the string with vertical.

Both the tension and the velocity are maximum at mean position, velocity is minimum at extreme position, where it becomes 0.
Hence, statement I and II both are correct and statement II is the correct explanation.
