(1) If both Assertion (A) and Reason (R) are True and the Reason (R) is a correct explanation of the Assertion (A).
(2) If both Assertion (A) and Reason (R) are True but Reason \( (\mathrm{R}) \) is not a correct explanation of the Assertion (A).
(3) If Assertion (A) is True but the Reason (R) is False.
(4) Assertion (A) is False but Reason (R) is True.
Assertion (A): Energy of an electron in \( \mathrm{n}^{\text {th }} \) orbit is \( \left(-13.6 \frac{\mathrm{z}^{2}}{\mathrm{n}^{2}} \mathrm{ev}\right) \) for one electron system atoms
Reason (R): Centripetal force is provided by electrostatic force between electron and nucleus and for stationary orbits \( \mathrm{mvr}=\mathrm{n}\left(\frac{\mathrm{h}}{2 \pi}\right) \)
