As the electron in Bohr orbit of hydrogen atom passes from state n=2 to n=1, the kinetic energy K and potential energy U change as :

A

A)K two-fold, U four-fold

B

B) K four-fold, U two-fold

C

C) K four-fold, U also four-fold

D

D)K two-fold, U also two-fold

Text Solution

Verified by Experts

The correct Answer is:
C
As `U = 2 E, K =- E`
Also, ` E =- (13.6)/(n ^(2)) eV`
Hence, K and U change as four-fold each.
