A bob of mass 'm' suspended by a thread of length 
undergoes simple harmonic oscillations with time period T. If the bob is immersed in a liquid that has density 
times that of the bob and the length of the thread is increased by 1/3 rd of the original length, then the time period of the simple harmonic oscillations will be:-
A
