The time period of 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:

Options

  1. AT 4
  2. BT
  3. CT 2
  4. D2 T

Correct answer

C. T 2

Step-by-step solution

Let K= force constant of spring and K^ = force constant of each part then gathered 1 K = 4 K^ K^ =4 K Time period =2 m 4 K = 1 2 2 m 4 K = T 2 gathered
