The linear displacement 'x' of the bob of simple pendulum from its mean position varies as x = a ( 2 t ) where 'a' is its amplitude expressed in metre and 't' is in second. The length of simple pendulum is (Take ' g ^ = ² ~m / s ² )
Options
- A1 5 ~m
- B3 0 ~m
- C2 0 ~m
- D2 5 ~m
Correct answer
C. 2 0 ~m
Step-by-step solution
x = a ( 2 t ) = 2 = 2 T T =2 2 ~T =2 g 2 2 =2 g 2= ² g = 2 ~g ² =2 ~m
