Question

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

(a) 1 : 1

(b) 1 : -1

(c) 2 : -1

(d) 1 : -2

Answer 1

The correct option is (b) 1 : -1.

Explanation:

In a Bohr orbit of the hydrogen atom, Kinetic energy = - (Total energy)

So, Kinetic energy : Total energy = 1 : -1
