In the graph between v and Z for the Mosley' equation, v = a Z - b , the intercept OX is 1 on v axis. What is the frequency v when the atomic number Z is 52?

Options

  1. A7.14 s - 1
  2. B7 s - 1
  3. C2401 s - 1
  4. D2601 s - 1

Correct answer

D. 2601 s - 1

Step-by-step solution

v = a Z - a b a b = 1 a = tan ⁡ 4 5 ° = 1 v = 52 - 1 = 51 v = 5 1 2 = 2601 s - 1
