Electrostatics Question 436

Question: In an hydrogen atom, the electron revolves around the nucleus in an orbit of radius $ 0.53\times {{10}^{-10}}m $ . Then the electrical potential produced by the nucleus at the position of the electron is [Pb. PMT 2001]

Options:

A) ? 13.6 V

B) ? 27.2 V

C) 27.2 V

D) 13.6 V

Show Answer

Answer:

Correct Answer: C

Solution:

$ V=9\times 10^{9}\times \frac{Q}{r}=9\times 10^{9}\times \frac{(+1.6\times {{10}^{-19}})}{0.53\times {{10}^{-10}}} $ = 27.2V
