Question:

When a hydrogen atom is raised from the ground state to fifth state

Options:

both K.E. and P.E. increase                                         

both K.E. and P.E. decrease

P.E. increases and K.E. decreases   

P.E. decreases and K.E. increases

Correct Answer:

P.E. increases and K.E. decreases   

Explanation:

As the number of orbit increases, the velocity decreases i.e., K.E. decreases. The potential energy becomes less negative i.e., P.E. increases.
