Question

For a body executing simple harmonic motion,

• A. Acceleration of the body is always directed towards the mean position.
• B. Acceleration of the body directly proportional to the displacement from the mean position.
• C. The total mechanical energy is constant at any point on its path.
• D. All the above

Answer 1

The correct option is D All the above

For a body executing simple harmonic motion :
Acceleration of the body is always directed towards the mean position.
Acceleration of the body directly proportional to the displacement from the mean position.
i.e. $a\propto -x$
And,
The total mechanical energy is constant at any point on its path.
