The kinetic energy of an electron in the ground state of a hydrogen atom is K . The values of its potential energy and total energy respectively are :
- A \(-2 K,- K\)
- B \(+2 K , - K\)
- C \(- K ,+2 K\)
- D \(+ K ,+2 K\)
Answer & Solution
Correct Answer
(A) \(-2 K,- K\)
Step-by-step Solution
Detailed explanation
Potential Energy \(PE = -2 \times \text{Kinetic Energy}\) \(PE = -2K\) Total Energy \(E = -\text{Kinetic Energy}\) \(E = -K\) Potential Energy, Total Energy = \(-2K, -K\)
