A simple pendulum of length 1 is made to oscillate with amplitude of 45 degrees. The acceleration due to gravity is g . Let T₀=2 l / g . The time period of oscillation of this pendulum will be

Options

  1. AT ₀ irrespective of the amplitude
  2. Bslightly less than T₀
  3. CSlightly more then T ₀
  4. DDependent on whether it swings in a plane aligned with the north-south or east west directions.

Correct answer

C. Slightly more then T ₀

Step-by-step solution

T=2 g (1+ ₀² 16 )
