Statement I: Two unequal springs of same material are loaded with same load. The longer one will have larger value of time period.
Statement II: The concept will follow, if we made a experiment to measure.

Easy

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

When a longer spring is loaded with weight mg, the extension l will be more. Therefore according to the expression $T = 2 π \sqrt{\frac{M}{k}}$ , the longer spring will have a larger value of the time period.
