Assertion: Bohr had to postulate that the electrons in stationary orbits around the nucleus do not radiate.
Reason: According to classical physical all moving electrons radiate.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Bohr postulated that electrons in stationary orbits around the nucleus do not radiate.
This is the one of Bohr's postulate. According to this the moving electrons radiate only when they go from one orbit to the next lower orbit.
