NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyA mass falls from a height 'h' and its time of fall 't' is recorded in terms of time period T of a simple pendulum. On the surface of the earth, it is found that t=2T. The entire set up is taken on the surface of another planet whose mass is half of that of the earth and radius is same. The same experiment is repeated and corresponding times noted as t' and T'. Then we can say:
1. t' =
2. t' > 2T'
3. t' < 2T'
4. t' = 2T'
