The kinetic and potential energy (in eV)...

The kinetic and potential energy (in eV) of an electron present in `2^(nd)` Bohr's orbit of hydrogen atom are respectively?

A

`-1.51, -3.02`

B

`3.40,-6.80`

C

`-3.02,1.51`

D

`6.80,-1.51`

Text Solution

Verified by Experts

The correct Answer is:
B
Total energy of third shell `=(-13.6)/(3^(2))= -1.51eV`
K.E. = -Total energy `rArr 1.51 eV, P.E. = 2 xx T.E.= -3.02 eV`
