Time period of a simple pendulum in Air is T. If the pendulum is in water and executes SHM, its time period is t . The value of T t is [density of bob is 5000 3 ~kg ~m ⁻³ ]

Options

  1. A2 5
  2. B2 5
  3. C5 2
  4. D5 2

Correct answer

B. 2 5

Step-by-step solution

For simple pendulum Time period in air, T =2 1 ~g ...(i) Time period in water, T =2 1 ~g (1- ) t =2 1 ~g (1- 1000 3 5000 ) = ( . 5 2 ) ) 2 1 g t = 5 2 ~T [ Using eq ( i )] T t = 2 5
