<h2 class="wp-block-heading" id="h-question-1-path-of-a-charged-particle-in-a-magnetic-field">Question 1: Path of a Charged Particle in a Magnetic Field</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>A charged particle enters a magnetic field at right angles to its velocity. What path does it follow?</p>
<!-- /wp:paragraph -->

<hr class="wp-block-separator has-alpha-channel-opacity"/>

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-concept">Concept:</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>When a <strong>charged particle enters a magnetic field perpendicularly</strong>, it experiences a magnetic force that continuously changes the direction of its velocity — causing it to move in a <strong>circular path</strong>.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This is because the <strong>magnetic force acts as a centripetal force</strong> on the particle.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> <strong>Option B – Circular Path</strong></p>

<p><strong>Question:</strong><br>What is the SI unit of magnetic field strength?</p>

<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-answer">Answer:</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>The SI unit of magnetic field strength is the <strong>Tesla (T)</strong>.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Also note: 1 Tesla=1 Weber/m21 \text{ Tesla} = 1 \, \text{Weber/m}^21 Tesla=1Weber/m2</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> <strong>Tesla</strong></p>

<h2 class="wp-block-heading" id="h-question-3-resistance-when-a-wire-is-stretched">Question 3: Resistance When a Wire is Stretched</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>A 2-meter-long wire has a resistance of 5 ohms. If it is stretched to double its original length, what will be its new resistance?</p>
<!-- /wp:paragraph -->
<!-- wp:separator -->
<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-key-formula">Key Formula:</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>When a wire is stretched, its volume remains constant. The resistance of a wire is given by: R=ρLAR = \rho \frac{L}{A}R=ρAL</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Where:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul class="wp-block-list"><!-- wp:list-item -->
<li>RRR is resistance</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>LLL is length</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>AAA is cross-sectional area</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>ρ\rhoρ is resistivity</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>When a wire is stretched to double its length, its <strong>area becomes one-fourth</strong> (since volume is constant).</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>So: R2=ρ2LA/4=4⋅ρLA=4RR_2 = \rho \frac{2L}{A/4} = 4 \cdot \rho \frac{L}{A} = 4RR2=ρA/42L=4⋅ρAL=4R R2=4⋅5=20 ΩR_2 = 4 \cdot 5 = 20 \, \OmegaR2=4⋅5=20Ω</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> <strong>20 ohms</strong></p>
