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
