A body tied a spherical pot with a string and suspended it on a clamp. He then filled it with water. Length of the string if `90cm` and diameter of the pot is `20 cm`. The pot is slightly displaced to one side and leave it to oscillate. Considering the above example as a simple pendulum (`g=9.8 ms^-2`)
What is the length of the pendulum?

A body tied a spherical pot with a string and suspended it on a clamp. He then filled it with water. Length of the string if 90cm and diameter of the pot is 20 cm . The pot is slightly displaced to one side and leave it to oscillate. Considering the above example as a simple pendulum ( g=9.8 ms^-2 ) Calculate the period of oscillation of the pendulum.
