According to Bohr's Model
(A) The radius of the orbiting electron is directly proportional to 'n'.
(B) The speed of the orbiting electron is directly proportional to '1/n'.
(C) The magnitude of the total energy of the orbiting electron is directly proportional to '1/n2'.
(D) The radius of the orbiting electron is directly proportional to 'n2'.
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 4
$ r = r_0 \frac{n^2}{z}$
$ v = \frac{c}{137} \frac{z}{n}$
$ E = E_0 \frac{z^2}{n^2}$
The correct answer is Option (4) → (B), (C) and (D) only
