STANDARD Physics Bohr's Model MCQ Question
Type: MCQ-conceptual-Medium-Class 11
In the previous question, find the potential energy of electron (in Joule) in the given state.
A
−4.36 × 10⁻¹⁴ J
B
−4.36 × 10⁻¹⁶ J
C
−4.36 × 10⁻¹⁷ J
D
−4.36 × 10⁻¹⁸ J
Correct Answer
Option D
Detailed Explanation
As, P.E. = −2 K.E. Here, K.E. = 13.6 eV = 2.18 × 10⁻¹⁸ J. Hence, P.E. = −2 × 2.18 × 10⁻¹⁸ J = −4.36 × 10⁻¹⁸ J.
