The length of the simple pendulum is made 3 times the original length. If ' T ' is its original time period, then the new time period will be
Options
- A3 T
- B3 ~T
- CT 3
- DT 3
Correct answer
B. 3 ~T
Step-by-step solution
The time period T of a simple pendulum is given by T = 2 L g , where L is the length and g is the gravitational acceleration. When the length increases from L to 3L , the new period becomes T_ new = 2 3L g = 3 2 L g = 3 T . The correct option is B , since it corresponds to 3 T .
