Assertion: There occurs a chain reaction when uranium is bombarded with slow neutrons.
Reason: When uranium is bombarded with slow neutrons more neutrons are produced

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 .

Text Solution

Verified by Experts

The correct Answer is:
a
When uranium is bombarded by slow neutrons the reaction is represented as `._92^235U + ._0^1n to ._56^144Ba + ._36^89Kr + 3_0^1n`+Energy
As more neutrons are produced , the reason is correct.
There are additional neutrons strike uranium nuclei to produce even more neutrons. Thus a chain reaction is established.
