A metre stick swinging in vertical plane about a fixed horizontal axis passing through its one end undergoes small oscillation of frequency `f_0`. If the bottom half of the stick were but off, then its new frequency of small oscillation woul become.

A metre stick swinging in vertical plane about a fixed horizontal axis passing through its one end undergoes small oscillation of frequency f_0 . If the bottom half of the stick were cut off, then its new frequency of small oscillation will become.

A metre stick swinging about its one end oscillates with frequency f_(0) . If the bottom half of the stick was cut off, then its new oscillation frequency will be :

A metre stick swinging about its one end oscillates with frequency f_(0) . If the bottom half of the stick was cut off, then its new oscillation frequency will be :

A metre stick swinging about its one end oscillates with frequency f_(0) . If the bottom half of the stick was cut off, then its new oscillation frequency will be :

A solid cube of side l is made to oscillate about a horizontal axis passing through one of its edges. Its time period will be

A magnetic needle vibrates in a vertical plane parallel to the magnetic meridlian about a horizontal axis passing through its centre. Its frequency is pi . If the plane of oscillation is turned about a vertical axis by 90^(@) , the frequency of oscillation in vertical plane will be :
