The string length of an instrument is 100 cm and fundamental frequency is 120 Hz. To get a fundamental frquency of 150 Hz, where it should be pressed ?

Explanation

To solve the problem, we need to determine where to press the string of the instrument to achieve a fundamental frequency of 150 Hz, given that the original length of the string is 100 cm and the fundamental frequency is 120 Hz.

### Step-by-Step Solution:

1. **Understand the relationship between frequency and length**: The fundamental frequency (ν) of a vibrating string is inversely proportional to its length (L). The formula for the fundamental frequency is given by:
\[ ν = \frac{k}{L} \]
