Question

5. The ratio of kinetic energy to potential energy of electron of H-atom is
a. 1:2
b. -1:2
1:1
d. -1:1
​

Answer 1

Hey, here ur ans is
As we have learned

Relation between K.E.,P.E. & total energy -

Potential Energy and total energy are negative .While kinetic energy is positive

 

For bohr orbit of hydrogen atom 

, Total energy of an electron = kinetic energy of an electron 


D-1 :2 is correct answer

Hope it will help u.....
