Question

Two masses m1 and m2 connected by a spring of spring constant k rest on a frictionless surface.If the masses are pulled apart and let go,the time period of oscillation is ​

Answer 1

Answer:

In this there is only one spring so spring constant is  K

But the masses are in series  so according to series formula

1/Mr = 1/M1 + 1/M2

        = M1 ×M2 /M1+M2

      T = 2π √M/K

         = 2π  √1/K × M1×M2 / M2+M2

         0ption first is correct
