1.	Two blocks of masses m and 2m rest on a frictionless horizontal surface. They are connected by an ideal spring of relaxed length l and stiffness constant k. By means of a massless thread connecting the blocks the spring is held compressed to a length l//2. the whole system is moving with speed v in a direction perpendicular to the length of the spring. the thread is then burnt. Answer the following questions in terms of l,km,v The time period of oscillation of the system is :
Answer» `2pisqrt((2m)/(3k))` `2pisqrt((3M)/(2K))` `2pisqrt((3m)/(K))` `pisqrt((2m)/(3k))` Answer :A
