A person normally weighing 50 kg stands on a massless platform which oscillates up and down harmonically at a frequency of `2.0s^(-1)` and an amplitude 5.0 cm. A weighing machine on the platform gives the persons wieght against time.
(a) Will there be any change in weight of the body, during the oscillation?
(b) If answer to part (a) is yes, what will be the maximum and minimum reading in the machine and at which position?

Explanation

To solve the problem step by step, we will analyze the oscillation of the platform and how it affects the reading on the weighing machine.

### Step 1: Understanding the Weight Change During Oscillation
The weight of a person on a weighing machine is the normal force exerted by the machine. When the platform oscillates, the acceleration of the platform changes, which affects the normal force and hence the reading on the weighing machine.

**Hint:** Consider how acceleration affects the normal force acting on the person.

### Step 2: Determine the Acceleration of the Platform
