JEE Main 2017 Physics question
A kg block attached to a spring vibrates with a frequency of Hz on a frictionless horizontal table. Two springs identical to the original spring are attached in parallel to an kg block placed on the same table. So, the frequency of vibration of the kg block is:
Answer: (4)
Solution
From the first arrangement,
= 1{2π} = 1\ Hz with = 1\ kg k = 2π.
Two identical springs **in parallel** share the displacement and add their forces, so the effective stiffness is . With kg,
= \
