Revision Notes on Deformable Bodies and Elastic Deformation (Mechanical Properties of Solids):-Matter:- Anything which possesses mass and occupies space is called matter. By : Samuelson • The Law of Demand states that Quantity Demanded Increases with a Fall in Price and Diminishes when Price Increases, other When the price falls he buys 1400 units. Ans. However, unlike elasticity of demand, elasticity of supply will always have a positive sign. 1 per unit. Within the limit of elasticity, the stress is proportional to the strain. This is a numerical based chapter on elasticity of demand, price elasticity of demand and its measurements, also discussing the factors affecting it. (b) NCERT Textbooks (c) Medicines (d) Air Conditioners Ans: D Q.5 Which of the following statements is incorrect: (a) Higher numerical value of elasticity means larger effect of a price change on the quantity demanded. dceta.ncert@nic.in 011 2696 2580 NCERT, Sri Aurobindo Marg, New Delhi-110016 011 2696 2580 NCERT, Sri Aurobindo Marg, New Delhi-110016 or Stress = E * Strain. y = FΔl / Al = Mg Δl / πr 2 l. Its unit is N/m 2 or Pascal and its dimensional formula is [ML-1 T-2]. Time – the longer the period of time, the more price elastic is the demand for a product. The expenditure on the goods is likely to increase if there is 10% increase in the price of goods considering that the elasticity of demand is - 0.2. %���� Although there are several standard textbooks to follow for the IAS exam for Economy, the basic books and the ones which are recommended if you are starting your IAS preparation are the NCERT textbooks.
