NEET Physics important Questions— Set 2 (Q11–Q20) — Solved (English + Hindi)

NEET Physics PYQ 2025 — Set 2 (Questions 11–20) — Solved (English + Hindi) Continuation of the NEET PYQ series. Ten original NEET-style questions with concise solutions in English followed by Hindi (Hinglish) notes. Series: Set 1 (Q1–Q10) • All NEET PYQs • Set 3 (Q21–Q30) Q11. Escape velocity from a planet of radius \(R\) and mass \(M\) is \(v_e\). If the planet's density remains constant but its radius doubles, the new escape velocity is proportional to: (Gravitation) (a) \(\sqrt{2}\,v_e\) (b) \(v_e\) (c) \(2v_e\) (d) \(v_e/\sqrt{2}\) Check / Show solution Answer — (d) \(v_e/\sqrt{2}\) English: Escape velocity \(v_e=\sqrt{2GM/R}\).

NEET Physics pyq 2025 Q1. A pipe open at both ends has a fundamental frequency \( f \) in air. It is now dipped vertically in water so that half of its length is filled with water. The new fundamental frequency of the air column is: \( \frac{f}{2} \) \( f \) \( \frac{3f}{2} \) \( 2f \) Check Answer Answer: \( \frac{3f}{2} \) Explanation: Half the pipe becomes an open–closed column ⇒ effective length becomes half ⇒ frequency increases by factor \( \frac{3}{2} \). Q2. Two identical masses oscillate vertically using springs of constants \( k_1 \) and \( k_2 \). If their maximum speeds are the same, the ratio of amplitudes \( \frac{A_Q}{A_P} \) is: \( 2k \) \( \frac{1}{k_2} \) \( k_2 \) \( \frac{k_1}{\sqrt{k_2}} \) Check Answer Answer: \( \frac{A_Q}{A_P} = \sqrt{\frac{k_1}{k_2}} \) Since max speed is \( v = A\omega = A\sqrt{k/m} \), same speed ⇒ \( A\sqrt{k} = \text{constant} \). Q3. A polaroid sheet is kept between two ...
