When a hydrogen atom is raised from the ground state to an excited state –
A
Both kinetic energy (KE) and potential energy (PE) increase
B
Both KE and PE decrease
C
PE increases, KE decreases
D
PE decreases, KE increases
Answer
PE increases, KE decreases
Explanation
Solution
As 'r' increase P.E increase but KE decrease
