Assertion (A): If distance between plates of charged and isolated parallel plate capacitor increases then force between plates decreases.
Reason (R): Capacitance of a sphere is given by (4 \pi \epsilon_0 R). where is the radius of the sphere.
Options
- AIf both Assertion (A) and Reason (R) are True and the Reason () is a correct explanation of Assertion (A).
- BIf both Assertion (A) and Reason (R) are True but Reason ((\mathrm{R})) is not a correct explanation of the Assertion (A).
- CIf Assertion (A) is True but the Reason (R) is False.
- DAssertion (A) is False but the Reason (R) is True.
Correct answer
D. Assertion (A) is False but the Reason (R) is True.
Step-by-step solution
)
So, Assertion is false but capacitorsphere is
We know (V=\frac{1}{4 \pi \varepsilon_0} \frac{q}{R})
(C=\frac{q}{\frac{1}{4 \pi \varepsilon_0} \times \frac{q}{R}}=4 \pi \varepsilon_0 R)$
