The electric potential due to the nucleus of the hydrogen atom at a distance of `5.3xx10^(-11)m` is 27.2 V. what is the potential due to the helium nucleus at the same distance?

Options

A. 27.2 V
B. 54.4 V
C. 13.6 V
D. 27.2 V

Answer

B

Explanation

`V=(1)/(4piepsi_(0))(q)/(r)` i.e., `Vpropq`
`therefore V` is doubled for helium i.e., V+54.4 V
