A wire frame in the shape of an equilateral triangle is hinged at one vertes so that it can swing freely in a vertical plane, with the plane of the `Delta` always remaining vertical. The side of the frame is `1//sqrt(3)m`. The time period in secods of small oscillations of the frmae will be-

A wire frame in the shape of an equilateral triangle is hinged at one vertex so that it can swing freely in a vertical plane, with the plane of the Delta always remaining vertical. The side of the frame is 1//sqrt(3)m . The time period in seconds of small oscillations of the frame will be-

A uniform semicircular ring of mass m and radius r is hinged at end A so that it can rotate freely about end A in the vertical plane as shown in the figure. Calculate angle made by line AB with vertical in equilibrium position and time period of small oscillation of ring.

A grassy field has the shape of an equilateral triangle of side 6m. A horse is tied to one of its vertices with a rope of length 4.2m. The percentage of the total area of the field which is available for grazing is best approximated by

A copper wire is wound on a wooden frame, whose shape is that of an equilateral triangle .If the number of turns of the coil per units length of the frame remains the same but the linear dimension of the frame is increased to 3 times , then the self inductance of the coil:

A wire is bent an an angle theta . A rod of mass m can slide along the bended wire without friction as shown in Fig. A soap film is maintained in the frame kept in a vertical position and the rod is in equilibrium as shown in the figure. If rod is displaced slightly in vertical direction, then the time period of small oscillation of the rod is
