How will you determine the period of oscillation of a mass without the use of a clock? You are given a weightless spring, a metre scale and a known mass.

Explanation

To determine the period of oscillation of a mass attached to a weightless spring without using a clock, we can follow these steps:

### Step-by-Step Solution:

1. **Set Up the Experiment**:
- Hang the weightless spring from a fixed point (like a ceiling) using a suitable support. Ensure that the spring is vertical and can oscillate freely.

2. **Attach the Known Mass**:
