Q127 / 180 · NEET 2018 · Physics

The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom is

A
$2 : - 1$
Correct answer
B
$1 : - 1$
C
$1 : 1$
D
$1 : - 2$

Solution

In Hydrogen atom, for an electron
undefined

\frac{K E}{E_{T o t a l}} = \frac{1}{- 1}

Hence, the correct answer is option: 'B'.
