JEE Main 2026 — Oscillations Question with Solution
JEE Main 2026 (28 January Shift 2)
Question
As shown in the figure, a spring is kept in a stretched position with some extension by holding the masses 1 kg and 0.2 kg with a separation more than spring natural length and are released. Assuming the horizontal surface to be frictionless, the angular frequency (in SI unit) of the system is :

Correct answer
D30
Step-by-step explanation
Two masses (1 kg and 0.2 kg) connected by a spring (k = 150 N/m) on a frictionless surface undergo oscillation about their center of mass.
This two-body problem reduces to SHM with reduced mass kg.
The angular frequency is rad/s.
This two-body problem reduces to SHM with reduced mass kg.
The angular frequency is rad/s.
