A small bob attached to a light inextensible thread of length `l` has a periodic time `T` when allowed to vibrate as a simple pendulum. The thread is now suspended from a fixed end `O` of a vertical rigid rod of length `3l//4`. If now the pendulum performs periodic oscillations in this arrangement, the periodic time will be

A small bob attached to a light inextensible thread of length l has a periodic time T when allowed to vibrate as a simple pendulum. The thread is now suspended from a fixed end O of a vertical rigid rod of length (3l)/(4) (as in figure). If now the pendulum performs periodic oscillations in this arrangement, the periodic time will be-

In a simple pendulum the period of oscillation (T) is related to the length of the pendulum (L) as

A simple pendulum has time period T. A uniform rod, whose length is the same as that of the pendulum, undergoes small oscillations about its upper end. Its time period of oscillation will be -

The time period of a simple pendulum in air is T . Now the pendulum is submerged in a liquid of density (rho)/(16) where rho is density of the bob of the pendulum. The new time period of oscillation is.

A trolley moves in horizontal direction with an acceleration a. A simple pendulum of length l is suspended from the roof of the trolley. The time period of the pendulum will be

The graph between time period ( T ) and length ( l ) of a simple pendulum is

The graph of time period (T) of a simple pendulum versus its length (I) is

The l - T^(2) graph of a simple pendulum is an shown in the figure. The time period of the pendulum of length 0.5 mm is
