Assertion : The periodic time of hard spring is less its compared to t

1.	Assertion : The periodic time of hard spring is less its compared to that of soft string Reason: The periodic time depend upon the spring constantA. If both assertion and reason are true and the reasopn is correct explanation of the assertionB. If both assertion and reason are true and but not the correct explanation of assertionC. If assertion is true but the reason is falseD. If both assertion and reason are false
Answer» Correct Answer - B From the relation `T = 2pi sqrt((m)/(k))`, where k is the spring constant `T = (1)/(sqrt(k))`…(1) As we know that the spring constant of heat spring large in comparing in that of the spring therefore from Eq. (1) spring is large in comparison to that at soft spring therefore from Eq. (1) the time period will be less then for hard spring in comparision to that of soft spring
