MCQ

Assertion : Two concentric charged shells are given. The potential difference between the shells depends on charge of inner shell.

Reason : Potential due to charge of outer shell remains same at every point inside the sphere.

✓
If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
B
If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
C
If Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

Answer

Correct option: A.

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

a
$\mathrm{V}_{\mathrm{A}}=\frac{1}{4 \pi \varepsilon_{0}} \frac{Q_{1}+Q_{2}}{R_{2}}$

$\mathrm{V}_{\mathrm{B}}=\frac{1}{4 \pi \varepsilon_{0}}\left(\frac{Q_{1}}{R_{1}}+\frac{Q_{2}}{R_{2}}\right)$

$\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{A}}=\frac{1}{4 \pi \varepsilon_{0}} Q_{1}\left(\frac{1}{R_{1}}-\frac{1}{R_{2}}\right)$
