  • what is the circumference of the fourth orbit ?
Multiple choice

what is the circumference of the fourth orbit ?

  1. 5λ .

  2. 2λ .

  3. 4λ .

  4. 3λ .

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This option is correct because;  , λ = h / mv . and from conservation of angular momentum we have = mvr = nh / 2π . => 2πr = nλ . in this case value of n is 4 . hence, this option is correct.
