The total energy of an electron in an atom in an orbit is `-3.4eV`. Its kinetic and potential energies are, respectively:

A

3.4eV, 3.4 eV

B

`-3.4` eV , -3.4 eV

C

`-3.4` eV , -6.8 eV

D

3.4 eV, -6.8 eV

Text Solution

Verified by Experts

The correct Answer is:
D
Total energy = -3.4 eV
KE =-(TE)= 3.4 eV
PE = 2(TE) = 2 (-3.4)=-6.8 eV
