 AB and CD are two ideal springs having force constant K1 and K2 respectively. Lower ends of these springs are attached to the ground so that the springs remain vertical. A light rod of length 3a is attached with upper ends B and C of springs. A particle of mass m is fixed with the rod at a distance a from end B.and in equilibrium, the rod is horizontal. Calculate period of small vertical oscillations of the system.

In a multiple-choice question, there are five alternative answers, of which one or more than one are correct. A candidate will get marks on the question if he ticks all the correct answers. The candidate decides to tick answers at random. If the candidate answers all 100 questions, what is the probability of marking exactly 30 answers correct.
