Oscillations Part 2

A block of mass 2‌kg is attached with two identical springs of spring constant 20N∕m each. The block is placed on a frictionless surface and the ends of the springs are attached to rigid supports (see figure). When the mass is displaced from its equilibrium position, it executes a simple harmonic motion. The time period of oscillation is ‌
