If force (F), velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are:-
Answer: D. [F V⁻¹ T]
Why: Force = mass × velocity / time, so mass = F·T/V, giving the dimensions [F V⁻¹ T].
In the Young's double-slit experiment, the intensity of light at a point on the screen where the path difference is λ is K, (λ being the wave length of light used). The intensity at a point where the path difference is λ/4, will be :-
Answer: C. K/2
Why: I = I_max cos²(φ/2) with I_max = K at path difference λ; at λ/4 the phase is π/2, so I = K cos²(π/4) = K/2.
Be²⁺ is isoelectronic with which of the following ions ?
Answer: B. Li⁺
Why: Be²⁺ has 4 − 2 = 2 electrons. Li⁺ (3 − 1 = 2 electrons) has the same count, whereas H⁺ has 0 and Na⁺, Mg²⁺ have 10.
Reason of lanthanoid contraction is :-
Answer: A. Negligible screening effect of 'f' orbitals
Why: 4f electrons shield the outer electrons very poorly, so the increasing nuclear charge pulls the outer shell inward across the series, shrinking the radii.
Which of the following is not a common component of Photochemical Smog?
Answer: D. Chlorofluorocarbons
Why: Photochemical smog contains ozone, PAN, acrolein, aldehydes and NO₂ formed by sunlight acting on NOx and hydrocarbons; chlorofluorocarbons are ozone-depleting agents, not smog components.
An aggregate fruit is one which develops from :
Answer: B. Multicarpellary apocarpus gynoecium
Why: In aggregate fruits, each free carpel of an apocarpous multicarpellary gynoecium becomes a fruitlet, giving a cluster of fruitlets from one flower (e.g. strawberry, Annona).
An alga which can be employed as food for human being is :-
Answer: B. Chlorella
Why: Chlorella is a protein-rich unicellular green alga used as a food supplement (single cell protein), while the other genera are not used as food.
Which one of the following is a non - reducing carbohydrate ?
Answer: B. Sucrose
Why: In sucrose the anomeric carbons of glucose and fructose are joined by the glycosidic bond, leaving no free aldehyde or ketone group, so it is non-reducing.
Tubectomy is a method of sterilization in which :
Answer: A. small part of the fallopian tube is removed or tied up.
Why: Tubectomy is female sterilisation: a small part of each fallopian tube is cut or tied, blocking passage of the ovum. Cutting the vas deferens is vasectomy.
Forelimbs of cat, lizard used in walking; forelimbs of whale used in swimming and forelimbs of bats used in flying are an example of :-
Answer: C. Homologous organs
Why: Forelimbs of cat, lizard, whale and bat share the same basic bone plan from a common ancestor but are modified for different functions, so they are homologous organs. (Adaptive radiation is also arguably defensible.)
The AIPMT 2014 paper (Set P) in our collection has 180 questions: 90 in Biology, 45 in Physics and 45 in Chemistry. All 180 questions are compulsory.
Each correct answer earns 4 marks and each wrong answer loses 1 mark. An unanswered question scores nothing.
The chapters that carried the most questions were Biological Classification (9), Plant Kingdom (6), Sexual Reproduction in Flowering Plants (5).
