Motion in a Straight Line MCQ questions with answers
The first 3 of 30 questions. Unlock the series for the rest, each with a solution.
Q1. Match Column I with Column II for straight-line motion. Column I: (a) slope of position–time graph, (b) slope of velocity–time graph, (c) area under velocity–time graph, (d) area under acceleration–time graph. Column II: (i) acceleration, (ii) displacement, (iii) change in velocity, (iv) velocity.
सीधी-रेखीय गति के लिए स्तंभ I का स्तंभ II से मिलान कीजिए। स्तंभ I: (a) स्थिति–समय ग्राफ की प्रवणता, (b) वेग–समय ग्राफ की प्रवणता, (c) वेग–समय ग्राफ के अंतर्गत क्षेत्रफल, (d) त्वरण–समय ग्राफ के अंतर्गत क्षेत्रफल। स्तंभ II: (i) त्वरण, (ii) विस्थापन, (iii) वेग में परिवर्तन, (iv) वेग।
- A. a–iv, b–i, c–ii, d–iii
- B. a–ii, b–iii, c–iv, d–i
- C. a–i, b–iv, c–iii, d–ii
- D. a–iv, b–i, c–iii, d–ii
Solution
The slope of an $x$–$t$ graph gives velocity and of a $v$–$t$ graph gives acceleration, while the area under a $v$–$t$ graph gives displacement and under an $a$–$t$ graph gives the change in velocity.
$x$–$t$ ग्राफ की प्रवणता वेग देती है और $v$–$t$ ग्राफ की प्रवणता त्वरण देती है, जबकि $v$–$t$ ग्राफ के अंतर्गत क्षेत्रफल विस्थापन देता है और $a$–$t$ ग्राफ के अंतर्गत क्षेत्रफल वेग में परिवर्तन देता है।
Q2. A boy walks $60\ \text{m}$ due east in $30\ \text{s}$ and then $20\ \text{m}$ due west in the next $10\ \text{s}$. For the whole trip, his average velocity and average speed are respectively
एक लड़का $30\ \text{s}$ में $60\ \text{m}$ पूर्व की ओर चलता है और फिर अगले $10\ \text{s}$ में $20\ \text{m}$ पश्चिम की ओर चलता है। पूरी यात्रा के लिए, उसका औसत वेग और औसत चाल क्रमशः हैं
- A. $1\ \text{m/s}$ and $2\ \text{m/s}$ / $1\ \text{m/s}$ और $2\ \text{m/s}$
- B. $2\ \text{m/s}$ and $1\ \text{m/s}$ / $2\ \text{m/s}$ और $1\ \text{m/s}$
- C. $2\ \text{m/s}$ and $2\ \text{m/s}$ / $2\ \text{m/s}$ और $2\ \text{m/s}$
- D. $1\ \text{m/s}$ and $1\ \text{m/s}$ / $1\ \text{m/s}$ और $1\ \text{m/s}$
Solution
Net displacement $=40\ \text{m}$ east in $40\ \text{s}$ gives average velocity $1\ \text{m/s}$, while total path $=80\ \text{m}$ in $40\ \text{s}$ gives average speed $2\ \text{m/s}$.
$40\ \text{s}$ में शुद्ध विस्थापन $=40\ \text{m}$ पूर्व की ओर होने से औसत वेग $1\ \text{m/s}$ मिलता है, जबकि $40\ \text{s}$ में कुल पथ $=80\ \text{m}$ होने से औसत चाल $2\ \text{m/s}$ मिलती है।
Q3. The position of a particle moving along a straight line is given by $x=3t^2+2t$ (in metres, with $t$ in seconds). Its instantaneous velocity at $t=2\ \text{s}$ is
एक सीधी रेखा में गतिमान कण की स्थिति $x=3t^2+2t$ (मीटर में, जहाँ $t$ सेकंड में है) द्वारा दी गई है। $t=2\ \text{s}$ पर इसका तात्क्षणिक वेग है
- A. $14\ \text{m/s}$
- B. $12\ \text{m/s}$
- C. $16\ \text{m/s}$
- D. $8\ \text{m/s}$
Solution
Instantaneous velocity is $v=\frac{dx}{dt}=6t+2$; substituting $t=2$ gives $v=14\ \text{m/s}$.
तात्क्षणिक वेग $v=\frac{dx}{dt}=6t+2$ होता है; $t=2$ रखने पर $v=14\ \text{m/s}$ मिलता है।
