Read the passage given below and answer the questions that follow:
India adopted a democratic approach to the question of diversity. Democracy allows the political expressions of regional aspirations and does not look upon them as anti-national. Besides, democratic politics allows parties and groups to address the people on the basis of their regional identity, aspiration, and specific regional problems. Thus, in the course of democratic politics, regional aspirations get strengthened. At the same time, democratic politics also means that regional issues and problems will receive adequate attention and accommodation in the policy-making process.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
