MHT CET 2025 Physics question
A vertical spring oscillates with period 6 second with mass m is suspended from it. When the mass is at rest, the spring is stretched through a distance of (Take, acceleration due to gravity, )
Answer: (D)
Solution
At equilibrium, kx=mg\Rightarrow\frac mk=\frac xg. The period of a mass-spring system , so . With :
