Question

# The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is?

A
2:1
B
1:1
C
1:2
D
1:1

Solution

## The correct option is D $$1: -1$$Since the relation between, K.E., P.E., and T.E. is given as $$-T.E. = K.E. = -P.E./2$$Ratio  $$K. E : T.E :: 1 : -1$$So, the correct option will be D.Physics
