To study the variation of T with l for a compound pendulum (Bar pendulum) and then to determine (i) the value of acceleration due to gravity (g) in the laboratory, (ii) position of centre of gravity of the bar, and (iii) the radius of gyration (K) of the bar about an axis passing through C.G. and perpendicular to its length.
Apparatus Required : Bar Pendulum, stop watch digital, knife edges fixed to a rigid supports and meter scale
