T 0 is the time period of a simple pendulum at a place. If the length of the pendulum is reduced to 1 16 times of its initial value, the modified time period is
Options
- AT 0
- B8 π T 0
- C4 T 0
- D1 4 T 0
Correct answer
D. 1 4 T 0
Step-by-step solution
T 0 = 2 π ℓ g New time period, T = = 2 π ℓ 16   g = 2 π 4 ℓ g T = T 0 4
