MHT CET 2023 Physics question
A spring has a certain mass suspended from it and its period for vertical oscillations is 'T₁'. The spring is now cut in to two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillations is now 'T₂' The ratio T₁/T₂ is
Answer: (B)
Solution
The period of a spring-mass system is . The spring constant is inversely proportional to the length of the spring. Cutting the spring into two equal halves doubles the spring
