State the laws of simple pendulum.

Explanation

Laws of simple pendulum : The time period of a simple pendulum.
Depends on the following laws :
(i) Law of length : For a given value of acceleration due to gravity, the time period of a simple pendulum is directly proportional to the square root of length of the pendulum.
`T prop sqrt(l) " "....(1)`
(ii) Law of acceleration : For a fixed length, the time period of a simple pendulum is inversely proporitonal to square root of acceleration due to gravity.
`T prop (1)/(sqrt(g)) " "....(2)`
