Assertion : In spring block system if length of spring and mass of block both are halved, then angular frequency of oscillations will remain unchanged.
Reason : Angular frequency is given by `omega = sqrt((k)/(m))` .

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct 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:
D
(d) `k prop (1)/("length of spring")`
If length is halved k will become two times.
from, `T=2pisqrt((m)/(k))`
Time period T will remain half for the given conditions.
