If the bob is a hollow spherical shell of radius R and length of the string is L.the time period of the pendulum is T1,now the bob is filled with water and now its time period is T2,further the water of the bob is completely free zed to ice and this phenomena doesnot produce any change in L.Now the time perod of the bob is T3.
Then T1/T2 is ><=1?
And T2/T3 is ><=1?
