Ans.1. A. $+6\times {10}^{-24}\text{J}$. The formula $U=-pE\cos \theta$ tells us that for parallel alignment, $\theta =0^{\circ }$, so $\cos \theta =1$. Thus, $U=-pE=-(3\times {10}^{-29})(2\times {10}^5)=-6\times {10}^{-24}\text{J}$. Any other magnitude, such as $-1.5\times {10}^{-24}\text{J}$, would come from an incorrect substitution or arithmetic error.

Ans.2. D. 3.2N s. To compute impulse, we must use vector velocities with proper directions. If upward is positive, then a ball moving downward has negative velocity. So, just before impact, $v_i=-10{\text{m s}}^{-1}$, and after rebound, $v_f=+6{\text{m s}}^{-1}$. The change in momentum is $\mathrm{\Delta }p=m(v_f-v_i)=0.2(6-(-10))=0.2\times 16=3.2\text{N s}$.

Ans. 3. C. 2.0 A. I = 5 V / 2.5 Ω = 2.0 A through the battery.

Ans.4. A. 120. mo=30/1.5=20, $m_e=25\mathrm{/}5+1=6$me=25/5+1=6, total $120$

Ans. 5. A. 200N, acting at the centre of mass located $2.5\text{m}$ from either end. For a uniform rod of mass $m$, the weight is given by $W=mg$. Substituting $m=20\text{kg}$ and $g=10{\text{m/s}}^2$ gives $W=20\times 10=200\text{N}$. The rod is uniform, so its mass is evenly distributed along its length, making the centre of mass at the midpoint of the rod.

Ans. 6. A. 0.01M Na₂SO₄

Ans.7. 1. Sugar ‘X’ is D-Fructose, as it matches all given properties: it is the major sugar found in honey (~38-40%), it is a keto sugar (ketose with ketone group), it exists in α and β anomeric forms due to mutarotation, and it is laevorotatory (D-(-)-fructose, specific rotation -92°).

Ans. 8. B. 10. C₄H₈O cyclic ethers (degree of unsaturation = 1) include epoxides (3-membered rings), oxetanes (4-membered), and tetra hydrofurans (5-membered), with structural isomers based on ring size/substitution and stereoisomers from chiral centers.

Ans.9. D. A larger fraction of molecules possess energy greater than or equal to E_a. With increasing temperature, the Maxwell–Boltzmann energy distribution flattens and shifts such that a greater proportion of molecules lie in the high‑energy region above E_a.

Ans.10. C. p-Methoxyaniline is most basic, p-nitroaniline is least basic.

Ans.11. 1. White color colonies will be selected.

Ans.12. A. Apoenzyme. When apoenzyme binds with its cofactor, the active holoenzyme is formed. So the protein portion is apoenzyme.

Ans.13. B. Chromosome 1. Human chromosome 1 is the largest human chromosome and contains the highest number of genes (around ∼2000–2500 protein‑coding genes).

Ans.14. A. Menarche. Menarche is the medical term for the first menstrual bleeding in a female, which occurs at puberty.

Ans.15. D. Bacterium. Eli Lilly used recombinant DNA technology in the 1980s to produce human insulin (brand name Humulin).
