Question

The hollow metallic bob of a simple pendulum is filled with water. Water comes out drop by drop through a small hole at the bottom of the bob. How will the time period change?

Answer 1

`" The period of simple pendulum does not change."`

Explanation:

`"We can calculate the period of the simple pendulum with "`
`T=2 pi sqrt(l/g)" formula."`

`"Where T period , l length of cord, g acceleration of gravity "`

`"As you see , Period does not depend on mass of bob."`

`"Therefore, the period of simple pendulum does not change."`

`"Notice: We recommend that you review the article on the link"` `"discussing the variable-mass pendulum problem."`
