Define simple pendulum.

Write the displacement variable in simple pendulum.

What is simple pendulum? Deduce an expression for the time period of simple pendulum.

Write the laws of simple pendulum.

Assertion : As the mass of simple pendulum increases, its periodic time increases. Reason : Periodic time of simple pendulum is T= 2pi sqrt((l)/(g)) .

At which position in the string of simple pendulum has maximum tension?

'Motion of simple pendulum from mean positionl for small displacement is a simple harmonic motion'' - Explain this statement.

A simple pendulum is suspended in a lift which is going up with an acceleration of 5 m//s^(2) . An electric field of magnitude 5 N//C and direction vertically upward is also present in the lift. The charge of the is 1 mu C and mass is 1 mg . Talking g=pi^(2) and length of the simple pendulum 1m, find the time period of the simple pendulum (in sec).

To measure gravitational acceleration by using simple pendulum, length of pendulum (0.8pm0.01) m and periodic time (2.5pm0.12) s. Find percentage error in measurement of g.

Statement-1 : In compound pendulum, if suspension point and centre of oscillation are mutually inter change, then no change in time period is obtained. Statement-2 : Length of equivalent simple pendulum remains same in both the case.
