A) \[2\pi \sqrt{\frac{m}{k}}\]
B) \[2\pi \sqrt{\frac{m}{2k}}\]
C) \[2\pi \sqrt{\frac{m}{3k}}\]
D) \[\pi \sqrt{\frac{m}{k}}\]
Correct Answer: B
Solution :
When the particle of mass m at O is pushed by y in the direction of A, the spring A will be compressed by y while spring B and C will be stretched by \[y=y\cos {{45}^{o}}.\]So, that the total restoring force on the mass m is along OAYou need to login to perform this action.
