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 :A. `2pisqrt((2m)/(3k))`B. `2pisqrt((3m)/(2k))`C. `2pisqrt((3m)/(k))`D. `pisqrt((2m)/(3k))`
