Expert Answer:

As we know
 Total energy = kinetic energy + potential energy
In atomic structure potential energy is electrostatic and for stability it must be negative and it dominates the kinetic energy
From Bohr atomic model we know P.E = 2 K.E ( magnitude wise)
So putting the values
-13.6 = x - 2x ( x is kinetic energy)
So kinetic energy =13.6 ev
Potential energy = -2× 13.6 = - 27.2ec
