Question

The ratio of the kinetic energy to the total energy of an electron in Bohr orbit is

• A. 1 : -1
• B. - 1 : 1
• C. 1 : 2
• D. 2 : -1

Answer 1

Answer: (A)

Since the relation between, K.E., P.E., and T.E. is given as
$<br/>-\text{ T.E. }=\text{ K.E. }=-\text{ P.E. }/2<br/>$
Ratio K.E : T.E :: $1:-1$
