Question

The KE of an electron in any stationary orbit of the hydrogen atom in accordance with Bohr's hypothesis is equal to-

• A. (1/2) (potential energy of electron in that orbit)
• B. – (1/2) (potential energy of electron in that orbit)
• C. Potential energy of electron in that orbit
• D. (–1) (potential energy of electron in that orbit)

Answer 1

Answer: (B)

– (1/2) (potential energy of electron in that orbit)

Answer 2

KE = $\frac { 1 } { 2 }$ $\frac{KZe^{2}}{r}$ Ž v = $\frac{KZe^{2}}{r}$Ž E = $–\frac{1}{2}$ $\frac{KZe^{2}}{r}$
