Farm subsidies are essential despite their financial burden for the following reasons:
Support for Marginal Farmers: Subsidies provide financial aid to small and marginal farmers, enabling them to access fertilizers, seeds, and irrigation facilities.
Stabilizing Food Supply: They help ensure consistent agricultural production, leading to food security for the nation.
Reducing Rural Inequalities: Subsidies mitigate income disparities in rural areas by supporting resource-poor farmers.

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?
