Question

A block of mass m is placed on a smooth table. Its two sides are attached to fixed walls by means of collinear horizontal springs of spring constant k₁ and k₂ (k₁ > k₂) as shown in the fig. The block is made to oscillate horizontally along the line of two springs. The frequency of its oscillation is :

Answer 1

Correct option (b)

Explanation:

Two springs are connected in parallel, so, the equivalent force constant 

k_eq = k₁ + k₂ 

So, frequency of oscillation is
