Type: MCQ-numerical-Medium-Class 11
The time period of a mass suspended from a spring is T. If the spring is cut into four equal parts and the same mass is suspended from one of the parts, then the new time period will be -
A
T/4
B
T
C
T/2
D
2T
Correct Answer
Option C
Detailed Explanation
The time period of a spring-mass system is T = 2π√(m/k). When the spring is cut into four parts, the spring constant becomes 4k, reducing the time period to T/2.
