A thin rectangular magnet suspended freely has a period of oscillation equal to `T`. Now it is broken into two equal halves (each having half of the original length) and one piece is made to oscillate freely in the same field. If its period of oscillation is `T^(')`, then ratio `T^(')/T` is

A thin rectangular magnet suspended freely has a period of oscillation equal to T . Now it is broken into two equal halves (each having half of the original length) and one piece is made to oscillate freely in the same field. If its period of made to oscillate freely in the same field. if its period of oscillation is 'T' , the ratio (T')/(T) is

A thin rectangular magnet suspended freely has a period of oscillation T in a uniform magnetic field . Now it is broken in two equal parts perpendicular to magnetic axis and one place is allowed to oscillate in the same field . If its period of oscillation is T' , then ration (T)/(T') is

A bar magnet suspended freely has period of oscillation of 2s. Now, the bar magnet is broken into equal halves and one-half is suspended to oscillate freely in the same magnetic field. Find the time period of oscillation of this half of the magnet.

A thin rectangular magnet suspnded freely has a period of oscillation of 4s . If it is broken into one of the pieces is suspened similarly . The period of its oscillation will be

A thin rod 30 cm long is uniformly magnetised and its period of oscillation is 4 s . It is broken into three equal parts normal to its length. The period of oscillation of each part is

A spring has a certain mass suspended from it and its period for vertical oscillations is T_(1) . The spring is now cut into two equal halves and the same mass is suspended from one of the half. The period of vertical oscillation is now T_(2) . The ratio of T_(2)//T_(1) is

A spring has a certain mass suspended from it and its period for vertical oscillation is T. The spring is now cut into two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillation is now

A mass suspended from a spring of spring constant k is made to oscillate with a time period T. Now, the spring is cut into three equal parts and the mass is suspended from one of the parts. What will be the new time period of oscillations?

On loading a spring with bob, its period of oscillation in a vertical plane is T. If this spring pendulum is tied with one end to the a friction less table and made to oscillate in a horizontal, plane, its period of oscillation will be :
