A block is suspended by a spring and allowed to oscillate vertically with small amplitude. Time period of oscillation is T. Now the spring is cut into two parts whose lengths are in the ratio 2 :3. The two parts of the spring are attached to the same block as shown in figure. The block is now slightly pushed to the right and released. The new time period of oscillation is
detailed solution
Correct option is B
In the first case, T=2πmKIn the second case, K1=(2+32)K=5K2 and K2=(2+33)K=5K3∴Keff=K1+K2=25K6∴T'=2πmKe=2πm25K/6=65TTalk to our academic expert!
