If the `P.E.` of an electron is `-68 eV` in hydrogen atom then find out `K.E.,E` of orbit where electron exist `&` radius of orbit.

If the P.E. of an electron in hydrogen atom is -27.2 eV , then its T.E. is

If the total energy of an electron is -1.51 eV in hydrogen atom then find out K.E,P.E. , orbit radius and velocity of the electron in that orbit.

If the total energy of an electron is -1.51 eV in hydrogen atom then find out K.E,P.E. , orbit radius and velocity of the electron in that orbit.

In the nth orbit, the energy of an electron E_(n)= -( 13.6)/(n^(2)) eV for hydrogen atom. The energy required to take the electron from first orbit to second orbit will be
