Correct option is B
In a simple harmonic motion, the acceleration is always directed opposite to displacement. Hence at highest point, acceleration will be maximum in downward direction. So, the pseudo force on the person will be maximum in upward direction. This makes the normal reaction on the weighing machine decrease and hence shows minimum readingSimilar Questions
