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 situation of the person standing on the oscillating platform and determine the changes in weight as the platform oscillates.

### Step-by-Step Solution

**Given Data:**
- Mass of the person, \( m = 50 \, \text{kg} \)
- Frequency of oscillation, \( f = 2.0 \, \text{s}^{-1} \)
- Amplitude of oscillation, \( A = 5.0 \, \text{cm} = 0.05 \, \text{m} \)
