| Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. |
| Assertion (A): Bohr postulated that the electrons in stationary orbits around the nucleus do not radiate. |
| Reason (R): According to classical Physics, all moving electrons radiate. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: B
Solution :
Option (B) is correct. Explanation: Bohr postulated that electrons in stationary orbits around the nucleus do not radiate. This is true. According to classical Physics, the moving electrons radiate only when they jump from a higher energy orbit to the lower energy orbit. So, the reason is false.
