Question

Assertion (A) In an atom, the velocity of electron in the higher orbits keeps on decreasing.
Reason (R) Velocity of electrons is inversely proportional to the radius of the orbit.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Both Assertion and Reason are false

Answer 1

Answer: (A)

Velocity of electorns is inversely proportional to the radius of the orbit.
Velocity $=2.18 \times 10^{6} \times \frac{Z}{n}$
