Problem

What is the (start text, i, end text) kinetic energy of the electron, and the (start text, i, i, end text) potential energy of the atom in the state, n, equals, 2?
(start text, i, end text) Kinetic energy, K, start subscript, 2, end subscript, equals
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, e, V, end text
(start text, i, i, end text) Potential energy, U, start subscript, 2, end subscript, equals
