Oscillations MCQ questions with answers
The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. A particle performs SHM with a period of 2π seconds and an amplitude of 4 cm. The magnitude of its maximum acceleration is:
एक कण 2π सेकंड के आवर्तकाल तथा 4 cm के आयाम के साथ सरल आवर्त गति करता है। इसके अधिकतम त्वरण का परिमाण है:
- A. 4 m/s²
- B. 0.02 m/s²
- C. 0.08 m/s²
- D. 0.04 m/s²
Solution
ω = 2π/T = 1 rad/s, and the maximum acceleration is ω²A = 1 × 0.04 m = 0.04 m/s².
ω = 2π/T = 1 rad/s, तथा अधिकतम त्वरण ω²A = 1 × 0.04 m = 0.04 m/s² होता है।
Q2. For small oscillations of a simple pendulum, which one of the following does NOT affect its time period?
एक सरल लोलक के छोटे दोलनों के लिए, निम्नलिखित में से कौन-सा एक उसके आवर्तकाल को प्रभावित नहीं करता?
- A. The length of the pendulum / लोलक की लंबाई
- B. The local acceleration due to gravity / स्थानीय गुरुत्वीय त्वरण
- C. The mass of the bob / गोलक का द्रव्यमान
- D. The effective gravity in an accelerating frame / त्वरित निर्देश-तंत्र में प्रभावी गुरुत्व
Solution
The period is T = 2π√(L/g), depending only on the length and the local acceleration due to gravity. It is independent of the mass of the bob (and, for small angles, of the amplitude).
आवर्तकाल T = 2π√(L/g) होता है, जो केवल लंबाई तथा स्थानीय गुरुत्वीय त्वरण पर निर्भर करता है। यह गोलक के द्रव्यमान से स्वतंत्र होता है (तथा छोटे कोणों के लिए, आयाम से भी)।
Q3. A particle executing simple harmonic motion has amplitude 5 cm. At a certain instant, its speed is exactly half of its maximum speed. The magnitude of its displacement from the mean position at that instant is:
सरल आवर्त गति करने वाले एक कण का आयाम 5 cm है। किसी निश्चित क्षण पर, उसकी चाल उसकी अधिकतम चाल की ठीक आधी है। उस क्षण माध्य स्थिति से उसके विस्थापन का परिमाण है:
- A. 5/√2 cm
- B. 5/√3 cm
- C. 2.5 cm
- D. (5√3)/2 cm
Solution
Using v = ω√(A² − x²) and v_max = ωA, setting v = v_max/2 gives A² − x² = A²/4, so x = (√3/2)A = (5√3)/2 cm. The other values correspond to common errors such as assuming x equals half the amplitude.
v = ω√(A² − x²) और v_max = ωA का उपयोग करते हुए, v = v_max/2 रखने पर A² − x² = A²/4 प्राप्त होता है, अतः x = (√3/2)A = (5√3)/2 cm। अन्य मान सामान्य त्रुटियों से मेल खाते हैं जैसे x को आयाम का आधा मान लेना।
