Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

Assertion is true but Reason is false

Both Assertion and Reason are false

Velocity of electorns is inversely proportional to the radius of the orbit.
Velocity $= 2.18 \times 1 0^{6} \times \frac{Z}{n}$
