Kater’s Reversible Pendulum

It is a compound pendulum constructed on a principle that centre of oscillation and centre of suspension are interchangeable.

It consists of a steel rod/ brass of 120 cm dia capable two adjustable edges facing each other. Two metal weights (made of iron cast / brass) of dimension 7.5 x 3.5 cm (length x diameter) and 3.5 x 3.75 respectively can be made to slide along the length of the bar and can be clamped in any position.

Two wooden weights exactly similar to metal weights can also slide along the bar. With the help of this apparatus we can find acceleration due to gravity at a place.
