The kinetic energy of the electron will not change. The value of potential energy andconsequently, the value of total energy of the electron will change.

The total energy of an electron in the first excited state of the hydrogen atom isabout –3.4 eV.What is the kinetic energy of the electron in this state?What is the potential energy of the electron in this state?

Energy of electron after collision isa.its acquired kinetic energyb.sum of its rest mass energy and kinetic energyc.its rest mass energy

The kinetic energy of emitted electron is E when the light incident on the metal has wavelength  λ.To double the kinetic energy, the incident light must have wavelength:

An electron is in an excited state in a hydrogen like atom. It has a total energy of −3.4 eV. The kinetic energy of the electron is E and its de Broglie wavelength is λ

Assertion (A) : An electron has a higher potential energy when it is at a locationassociated with a negative value of potential and has a lowerpotential energy when at a location associated with a positivepotential.Reason (R) : Electrons move from a region of higher potential to a region oflower potential.
