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 true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
`k prop (1)/(l) rArr omega = sqrt((k)/(m))`
`:. omega prop (1)/sqrt(ml)`
It `m` and `l` both are halved then `omega` will become `2 times`.
